Hello
can someone please verify this answer for me?
(1+cotA) / (cscA)
(1+cosA/sinA) / 1 * (sinA/1)/1
answer is CosA
I don't follow what you did with the denominator? If you recall the way of dividing fractions we treat it as multiplying
$\displaystyle \left(1+\frac{cosA}{sinA}\right) \times sinA$
$\displaystyle \left(\frac{sinA+cosA}{sinA}\right) \times sinA = sinA + cosA$
edit: the answer cannot be $\displaystyle cosA$ because the identity doesn't hold for $\displaystyle A = \frac{\pi}{2}$
