Question

If Cos A = 1/√2, then Cosec 2 A=

Answer 1

so draw a triangle... you know the adjacent is 1 and the hypotenuse is sqrt 2

find the other side... not hard.

then find sin of the angle..

and take the reciprocal to find cosec

Answer 2

so is it

\[cosec^2(x) \]

if it is, square your answer
