The way I remember sinus, cosinus and tangent (in German): G-A-GA. * G-egenkathete/Hypotenuse * A-nkathete/Hypotenuse * G-egenkathete/A-nkathete In English it would be O-A-OA: * o-ppsite/hypotenuse * a-djacent/hypotenuse * o-ppsite/a-djacent

Hi Eddie! Love your videos so much, Thankyou for uploading them! Also, do you recommend a certain type of text book for the hsc?

My initial thoughts for the inverse function would be to express x in terms of y e.g. x=3y+2 i.e. f(y) but I can understand why the form f(x) was maintained.

This method swapping y=x completely destroy your into to inverse function idea method i.e reverse operation

Solve these Problem 1 If x+y+z=π\ x+y+z=\pix+y+z=π prove the trigonometric identity cotx^2+coty^2+cotgz^2=cotx^2coty^2cotz^2\displaystyle cot{\frac{x}{2}}+cot{\frac{y}{2}}+cotg\frac{z}{2}=cot{\frac{x}{2}}cot{\frac{y}{2}}cot{\frac{z}{2}}cot^2x+cot^2y+cotg^2z=cot2xcot2ycot2z Problem 2: Find the maximum value of 5cosA + 12sinA + 12

That second one is pretty easy. When you have a linear combination of sine and cosine of the same frequency, the amplitude of the combined sinusoid is simply the Pythagorean theorem combination of both amplitudes. So the maximum value of 5*cos(A) + 12*sin(A) + 12 is 13 + 12 = 25.
