Lol this is so my son (10) who has his own Google account. I think it’s so cute 🥰 it tickles me every time I see his comments with my face beside them.
Wow, This is quite easily explained than my Geometry Teacher I'm a slow person on understanding this and I'm already failing Geometry but this video have shown me some mistakes that I've done
want to pass algebra but taking a placement test in my new school in 4hrs so trying my luck to see if I can pass both algebra 1 and geometry but my priority is to pass algebra 1
The story with the root of 2 is the basis for the paper formats: DIN A1 => A2 => A3 => A4, etc. The length and width of the sheets are in a ratio of 1 : root 2 to each other.
Special angles. Just memorize the ff: sin 30=0.5, sin 45=0.707, sin 60=0.866. In cos 30 45 and 60 just derived it in SOHCAHTOA. With respect to the sides use pythagorean theorem.
It clicked for me way back when I realized this about sin 0-30-45-60-90: sqrt(0)/2; sqrt(1)/2; sqrt(2)/2; sqrt(3)/2; sqrt(4)/2. Seems crazy to write like that maybe, but the pattern becomes clear.
Also the other thing I NEVER knew when I was in school is that cos(θ) = sin(β), where θ is 1° thru 89º and β is 90 - θ. So, 10 * cos(60) = 10 * sin(30). So if you want to know the third side, you have to do 10 * sin(60) or 10 * cos(30). Another thing that can be used is radians versus degrees and knowing how to convert between them. To get radians, divide by 180 and multiply by π. To get degrees, divide by π and multiply by 180. rad = radians 180° = π rad 90° = π/2 rad 60° = π/3 rad 45° = π/4 rad 30° = π/6 rad 15° = π/12 rad
@@Fleebus θ and β are like variables that represent the angle in either degrees or radians, and so if θ is equal to 1 to 89 degrees, β would be equal to 90 - θ. SOH means Sin(θ) is equal to the Opposite side of the angle divided by the Hypotenuse. CAH means Cos(θ) is equal to the Adjacent side of the angle divided by the Hypotenuse. TOA means Tan(θ) is equal to the Opposite side of the angle divided by the Adjacent side. The Sin(θ) of one angle will be equal to the Cos(β) of the other angle. Therefore, 10 * Sin(60) is equal to 10 * Cos(30).
Triginometry? Horse manure! Trig certainly has its place, but when utilised in plane geometry it smacks of smugness of "the new math", i.e. needlessly complicating a simple problem. The sum of triangular angles must always equal 180°. In the case of any right triangle: X = (180 -- 90) -- Y X = 90 -- Y X = 90 -- 45 X = 45
Im currently takeing my ged i have passed the 3 other subjects and back in 2020 i took the math and missed it by 2 points my score was 143 i was so disappointed and frustrated after failing and never started it again till here about 1 month ago. Im currently having problems with the Geometry part of the test. Please help I test this Sunday.
Hey, you could have figured this out already, noting the 3 weeks, however I’d like to help anyway. The way he got 9 and 16 was because he put the two sides, 3 and 4, to the power of 2. Allow me to put it this way so you can see it. 3^2 -> 3x3 = 9 4^2 -> 4x4 = 16 He just input the numbers into the equation, a^2+b^2=c^2 and simplified
i thought it was a 3,4,5 for a 30. 60, 90 and 1, 1, radical 2 for a 45, 45, 90...the 2x didn't make sense for the 30, 60, 90 triangle...what did I miss???
Since we're dealing with right triangles let's cut right to the chase hypotenuse question mark squared equals x squared plus adjacent? squared. 30 seconds compared to 14 minutes. May I ask, are you in the business of teaching or confusing?
Wish me luck on my geometry exam! I got it tomorrow (June 21st) definitely gonna need some extra luck!
Did you pass lad
@@jakemorgan7242 yea!! I barely did- but I passed!!
@@CloudyHead ayy go on, got an exam to get into engineering coming this Thursday and I'm nervous
@@jakemorgan7242 you got this!! Try to study then the day before take it as a relax day. You won’t learn if you’re stressed
@@CloudyHead I passed 🎉🎉🎉
Wish me good luck on my test in 4 hours!!
This helped me get a high 3 Thank you!!!
I am also struggling with geometry thanks for putting your video in this world

Same for me
This is gonna be great learning for my trig and physics review. I always knew the Pythagorean theorem way but know this short cut is even better.
I am watching this before school even starts so I don’t struggle a ton
This helps with the Asvab as well, thank you for the free education sir. Knowledge is power!
Great lesson.
I was struggling with this back then; Time to do some review
I'm failing math at geometry like finding volume like a triangle that has an area base and hieght also 3d and 2d shapes 6th grade math
Oh my gosh, you are so big brain. Thank you very much sir.

99 percent advertisement 1 percent teaching
This was so easy to understand, I have my eoc tomorrow. Thanks for the vid! It helped a lot, you are so good at explaining in such a simple way 🙏
same
So how did it go? Lol
I have my EOC today and I'm barely studying at 6 AM

i have my exam in 2 hours so i can take alegbra 2 in 9th. this video helped my review
hyp.=2x and other x root 3/2
im just trying to get grasp for summer school to advance

What does any of this mean 😭 it’s over for me 💀

What are all of your web sites sir?
It really helped me out
Guys wish me luck Tuesday for my Geometry EOC!!! I’m really going to need some extra luck as FLVS wasn’t that great! Thanks!!!

Oh wow… looks like someone needs some trigonometry.

It depends as rick can probably out run him with his tech but would 096 be able to travel to other universes to get rick.
What happened to multiplying by 1.414?
Just doing math need a lot of help with graphs
Can you provide on the median mode mean Thanks very much
Organic Chemistry Channel is way better I’m out 3:45
You are urgently needed in the john. Don't forget to take sand paper because we are out of toilet paper
Thank you for the help sir 👏🏼👏🏼👏🏼
Biswa brahmande kon hoi na.
As per maths.
can someone please help me understand where 9 and 16 come from on 5:08 .. im new to geometry
Hey, you could have figured this out already, noting the 3 weeks, however I’d like to help anyway. The way he got 9 and 16 was because he put the two sides, 3 and 4, to the power of 2. Allow me to put it this way so you can see it.
3^2 -> 3x3 = 9
4^2 -> 4x4 = 16
He just input the numbers into the equation, a^2+b^2=c^2
and simplified
Weeeeh ..mwalimu wa maths hapa ni wapi
I'm absolutely terrible with geometry & want to know how you got 9 in the a + b = c?
It’s squared so it’s 3x3x3
For 30-60-90:
X=1, sides are square root of 3, and 2.
For 45-45-90:
X=1, sides are 1 and square root of 2.
i am taking my geometry exam tomorrow
Class 10 teaching sir
This was Really Good.
it remindes me thanks
Wish me luck this year all i want is to pass i jus need 24.7 to pasß regents
Great! Thank you.
I always remember 3 4 5 and 5 12 13 as ratios but not the angles!
i thought it was a 3,4,5 for a 30. 60, 90 and 1, 1, radical 2 for a 45, 45, 90...the 2x didn't make sense for the 30, 60, 90 triangle...what did I miss???
huh i dont understand
(60x+30x)= (90 +90) 180
first x=adj x√3=hyp hyp = 2x second x=adj x=hyp x√2=hyp
4:22 video starts
But how did you come to the square root of 3 for the special triangle??? Is that the answer or should I actually find what the square root of 3 is???
Good video John
Great video
Please wish me good luck
Got a 78 W
I wish some one would have taught me this trick when I was in 10th grade
Excelente video
It's trigonometry, plain and simple.
Well it can get more simple if you just memorize these two triangles
it was not understood
I learned something! Thanks!
Brilliant explanations 👍👍👍
(45x+45x+)= (90x+90)= 180
it makes no sense 🤦♂
I have a regent tomorrow
too complicated
Since we're dealing with right triangles let's cut right to the chase hypotenuse question mark squared equals x squared plus adjacent? squared. 30 seconds compared to 14 minutes. May I ask, are you in the business of teaching or confusing?
I’m so scared for those geometry regents in January. Please wish me luck!!
I am taking Algebra 1 and somehow I already knew this.💀
A2 + B2 = C2 which is literally the most irrelevant theory on the face of the planet. Tell me one person ever who has looked for C2? Please? Just one.
Talk talk!
The first one is 180 °?
And second one is 180°
Am I correct
All triangles add up to 180 degrees so that would have to be correct.
Sooo ez
