Question

Simplify the following expression $\frac{{\sin }^2\theta +{\cos }^2\theta }{\sin \theta +\cos \theta }$

Answer 1

On simplifying, we get

$\frac{{\sin }^2\theta +{\cos }^2\theta }{\sin \theta +\cos \theta }$ ...........As, $(si{n}^{2}x+co{s}^{2}x=1)$

$⟹\frac{1}{\sin \theta +\cos \theta }$
