Ravi is asked to show that √1 - A/1 + A equals one of the standard ratios for an acute angle A. Which expression does it equal?

Question

Accepted Answer

cosec A - cot A. Multiply numerator and denominator inside the root by (1 - cos A): √(1- A)^2/1 - ^2 A = √(1- A)^2/ ^2 A = 1 - A/ A = 1/ A - A/ A = cosec A - cot A.
