You've helped me so much with math it's actually crazy. Certain topics I just couldn't learn until I found you. This video showed up in my recommendations and I had to show some support. Keep it up man, you're truly helping more people than you could imagine. Have a nice day!
Bro this is literally the best teaching I’ve ever received like it took my teacher 2 lessons and it still didn’t make sense and in literally like 3 minutes with one method I was able to speed through the homework
Personally, I think that finding trig values for (pi/6) radians (30 degrees), (pi/4) radians (45 degrees), or (pi/3) radians (60 degrees) is easier when using the special right triangles (i.e., the 45-45-90 (which is isoceles) right triangle and the 30-60-90 right triangle), as opposed to using the unit circle (It isn't easy to memorize all of the points on the Unit Circle). Then, if an angle is a reference angle to one of these angles in another quadrant (i.e., that many degrees away from the x-axis), then I remember this acronym: All Students Take Calculus (explained below), because the trig values will be almost exactly the same, only (possibly) differing by the sign (i.e., whether it is positive or negative). All: In the first quadrant (i.e., in Quadrant I), All six trig functions (i.e., sin(x), cos(x), tan(x), csc(x), sec(x), and cot(x)) (Notice how the "A" is capitalized) are positive. Students: In the second quadrant, only Sin(x) (Hence, also csc(x)) (Notice how the "S" is capitalized) are positive. All of the other four trig functions are negative, in Quadrant II. Take: In the third quadrant, only Tan(x) (Hence, also cot(x)) (Notice how the "T" is capitalized) are positive. All of the other four trig functions are negative, in Quadrant III. Calculus: In the fourth quadrant, only Cos(x) (Hence, also sec(x)) (Notice how the "C" is captialized) are positive. All of the other four trig functions are negative, in Quadrant IV. I only use the Unit Circle to evaluate trig values for quadrantal angles (i.e., 0 radians (0 degrees), (pi/2) radians (90 degrees), pi radians (180 degrees), ((3*pi)/(2)) radians (270 degrees), 2*pi radians (360 degrees), etc.). From there, you remember that, on the Unit Circle, the x-coordinate of the point is the cosine of the angle, and the y-coordinate of the point is the sine on the angle.
this man in 10 minutes has taught me more than my busy work teacher could in 70 minutes
this man in 10 minutes has taught me more than my busy work teacher could *not* in 70 minutes
@@ibraheemayub3894 This man has taught me in just 10 min more than my teaher could in 70 min.

you have a real gift, teaching is difficult but you make it so easy for me to understand
You're a legend, you also help me alot with my math !!
You explain things so well. Thankyou!!!

Glad it helped!
One of the best math channels without you i probably would have failed school XD

This helped me so much! I would’ve failed my test without you 😬
The best math video.
Thw short cut method just help me understand this completely. I had to play in .5 for personal learning but very helpful.!!!
Glad it helped!
Thank you so so much man I really appreciate these videos, helps study for my math tests!
Thank you so much!💗💗
Hi sir. Good to see your video everytime
so helpful .thank youuu!!
THANK YOU SO MUCH!!!!!
You're welcome!
Thank You soooo much u helped me i was very scared from this lesson bc tomorrow is my Exam ❤️❤️
Thank you so much you are a legend
Best math vids
Excellent
thank u mario.
Why didn't my teacher just teach us the shortcut method lmao. WAY easierrrr
Amazing
te quierooooooo
White Lighting way better. Black lettering better. Great instruction
Pog man pog
My teacher recommended you lol
Why do you sound like Nick Cage
King
I like ya cut G
Aha
