If you use for cot(A); and for tan(A), and do the algebraic steps, that will lead you to:

and then

Use of the basic pythagorean identity,

which is all in terms of sines.

Do you mean in terms of sines?

(cotA + tanA)^2 = (cos/sin + sin/cos)^2 = ((cos^2 + sin^2)/(sin*cos))^2
= 1/(sin(A)*cos(A))^2
= 1/(2sin(2A))^2
