Answers: 2
![\bf \cfrac{\underline{[sin(\theta )+cos(\theta )]}~~[sin^2(\theta )-sin(\theta )cos(\theta )+cos^2(\theta )]}{\underline{sin(\theta )+cos(\theta )}}+sin(\theta )cos(\theta ) \\\\\\ \cfrac{sin^2(\theta )-sin(\theta )cos(\theta )+cos^2(\theta )}{1}+sin(\theta )cos(\theta ) \\\\\\ sin^2(\theta )\underline{-sin(\theta )cos(\theta )}+cos^2(\theta )\underline{+sin(\theta )cos(\theta )} \\\\\\ sin^2(\theta )+cos^2(\theta )\implies 1](/tpl/images/0139/0963/aead0.png)
