Question

solve this question where theta is acute anglethen value of sinsq theta

Answer 1

\[\sec \Theta+\tan \Theta =2\]

Answer 2

\[\frac{1}{\cos \theta}+\frac{\sin \theta}{\cos \theta}=2\]
\[1+\sin \theta=2\cos \theta \]
\[1+2\sin \theta +\sin ^2\theta =4\cos ^2\]
\[1+2\sin \theta +\sin ^2\theta =4(1-\sin ^2\theta )\]
\[5\sin ^2\theta +2\sin \theta -3=0\]
\[(5\sin \theta -3)(\sin \theta+1)=0\]
