that side note of telling us to make sure we are in degree mode on our calculator was SUPER HELPFUL !!! Thank you for posting this. It helped me greatly. Thank you.
had a question that had me absolutely lost for a little bit but eventually I got it. A plane is at an altitude of 400m, the pilot looks down at a landmark at an angle of depression of 1.5 degrees, two minutes later, the angle of depression was 5 degrees. The question asked to find the speed of the plane in km/h. To me that sounded like a "there were 4 boys and 6 apples, how many seals were at the zoo" type of impossible question. For a solid 5 minutes I stared at the question thinking "what the actual f*ck am I meant to do" and then it clicked lol. It's 321.1km/h I believe
Hi Mario. I was wondering if you could help with some math homework. Q: A lifeguard spots a swimmer in the lake at an angle of depression of 45°. He spots a sailboat, further out, at an angle of depression of 26°. If the lifeguard is 36.5 dm away from the swimmer and 84.7 dm away from the sailboat, how far is the swimmer from the sailboat? The difference between your question and mine is I don't know the height of where the lifeguard is sitting. Would I instead use cosine to find x?
Hello Mario! Could you please give some techniques to add or subtract numbers mentally faster? What is intereresting is that I tend to multiply and divide faster mentally 😄. Thank you!
“Solve for d” happens at about 2:50 d is the difference between the sea level distance between the plane and the first ship, and the plane and the second ship. That’s the distance between the ships, in this simplified 2-dimensional problem.

Thank you for posting this. It helped me greatly. Thank you.
You're welcome! I'm glad you found the video helpful. 👍
I was just doing my home work and i found you, and you have no idea of how I like it. Thanks very much!!!
Great.
But for the sake of beginners, stop being, stop rushing fast. 👍
You sir, is a life saver.
sir u really out here saving lives
2:58 : where did u get the value of “D”???
it’s the value of tan10°(d) so d doesn’t really have value yet
Brilliant video, I needed this for my 9th grade trig exam.
Hi sir, could you please explain how you extracted the value of D from the calculator?
tan(10)
thank you! what about if the boats are in two opposite sides?

This was great, Thank You!
Thanks for the teaching sir
Thank you so much sir!!😊
Most welcome 😊
Great video. Where did this problem you solved come from?
Just assuming
great video, really helped
Thank you for the video Mario
thank you so much sir!
mario u got me full marks on my hw ty pookie
I'm putting 37320.5tan(10) and I get 24197.2 in 2:49. what am I doing wrong?
Hi Mario.

Sorry no
Thank you so much omg !!!
Welcome!!
this
was the best
Glad you liked the video Yaser!

Hi Gabriella, good question! I don’t have a video on that topic yet but I’m glad you are looking at upleveling your skills!
@@MariosMathTutoring Thank you!!! Yes, I am looking for that! You may call me Gabby!
Hello sir can you please make a video on rational numbers 💖
And their operations💖💖
Thankyou
Thanks
How did find d stop going fast and explain
how did you get D? you got 1.76 but didn’t really explain where you got it from?
Same question here
It's tan(10°) bruh. Try it to your calculator and you'll get the answer
D represents another variable to make it clear that they don't use same variables.
“Solve for d” happens at about 2:50
d is the difference between the sea level distance between the plane and the first ship, and the plane and the second ship. That’s the distance between the ships, in this simplified 2-dimensional problem.
Check inside your pants you'll find d
Why is it so dam hard to find a video with just 2 angles of depression and no sides? Fuck I hate math
why are you adding D? Wouldnt distance mean you would subtract d from x?
Sir how to fin the tan 10 x d???
I like ya cut g
when i inputted 10000tan(15) i got 2679.491924 ??? i dont know what im doing wrong :(
Divide 10,000 by tan 15 (0.267949) = 37,320.5
tan(10) x (37320,5)=6580,6
Hi can u help me with my homework :3
Transform the following to matrices to RREF
A=[ 3 2 2 ]
-2 0 1
1 -1 0
B= [ 1 2 3 4 ]
-2 4 -3 5
3 0 5 -3
I did a video on the topic here: Row Reduced Echelon Form th-cam.com/video/yWO2vYn-TX4/w-d-xo.html

I'm in Clac 3, why am I here?

Using calculator is a sin. It's illegal
hoi kalbo
I don't understand
Which part?
Horizaul🤣
wtf
