Question

Which expression is equivalent to cot t sec t?

Answer 1

$\bf cot(\theta)=\cfrac{cos(\theta)}{sin(\theta)} \qquad % cosecant csc(\theta)=\cfrac{1}{sin(\theta)} \qquad % secant sec(\theta)=\cfrac{1}{cos(\theta)}\\\\ -------------------------------\\\\ cot(t)sec(t)\implies \cfrac{\underline{cos(t)}}{sin(t)}\cdot \cfrac{1}{\underline{cos(t)}}\implies \cfrac{1}{sin(t)}\implies ?$
