Question

express sinA in terms of cosA​

Answer 1

SinA = (1- Cos^2A)^1/2

Hope it helps❤️

Answer 2

Answer:

Step-by-step explanation:

cos a = square root of (1- square of sin a) 

tan = sin a / cos a = sin a/(square root of (1- square of sin a)) 

cosec a = 1/sin a 

sec a = 1/cos a = 1/(square root of (1- square of sin a)) 

cot a = cos a /sin a = (square root of (1- square of sin a))/sin a
