HOW TO LEARN THE TRIGNOMETRIC RATIOS OF COMPLEMENTARY ANGLES?

Expert Answer:

remember that in a right triangle with sides a,b,c where c is the hypotenuse. angles opposite to sides a and b are  complementary. so the sine of the angle opposite to side a naturally becomes the cos of its complementary angle, the angle  opposite to side b.This is the logic behind t-ratios of complementary angles.

So, just draw a right triangle and observe how this happens. That should clear the idea.
