Question

What is the answer to number 39 and

Answer 1

`\bf \cfrac{sec(\theta)-csc(\theta)}{sec(\theta)}\implies \cfrac{(1)/(cos(\theta))-(1)/(sin(\theta))}{(1)/(cos(\theta))}\implies \cfrac{(sin(\theta)-cos(\theta))/(cos(\theta)sin(\theta))}{(1)/(cos(\theta))} \\\\\\ \cfrac{sin(\theta)-cos(\theta)}{cos(\theta)sin(\theta)}\cdot \cfrac{cos(\theta)}{1}\implies \cfrac{\boxed{?}}{\boxed{?}}`
