Question

Express Tan A in terms of Sin A.

Answer 1

tanA=sinA/√1-sin square A

Answer 2

We know that Sin²A+Cos²A=1

So, Cos²A= 1-Sin²A

=> CosA= √1-Sin²A          

We know that Tan A=SinA/CosA            ..................Eq.(1)

On substituiting the value of Cos A in Eq.(1) we get

Tan A = SinA/√1-Sin²A
