Introduction of Trigonometry G 11

sin²x+cox²x= sec²x-tan²x =cosec²x-cot²x

Trigonometry ratio and trigonometry functions are different at primary level

If tan90 is infinity then cot90 =

Trigonometry mean measure of two side of triangle w.r.t angle

Function is a process which take input value and product out put with respect to input

under unit circle x =cosA and y = sinA where A is angle at _____

Sine ratio is __________ at [0, 90]

sin²30+cos²60=1

In trigonometry rationalisation is not possible

sinA/tanA
