If sin A = x, then what is the value of tan A in terms of x?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. x(1−x2) \frac{x}{\sqrt{(1-x^2)}}.

sin A = x

cos A = 1−x2\sqrt{1 − x^2}

tan A = sinAcosAsin A \over cos A = x(1−x2) \frac{x}{\sqrt{(1-x^2)}}
