Question

simplify the trig identity. 1-((cos^2 theta)/(1+sintheta))=sin theta

Answer 1

Sure the question is correct? @ashmibri

Answer 2

yes i'm sure

Answer 3

Please just check one more time.

Answer 4

\[1- (\cos ^{2}\theta \div 1+\sin \theta) = \sin \theta \]

Answer 5

PROVED IT!

Answer 6

\[1-\frac{ \cos^{2}\theta }{ 1+\sin \theta}\]

Answer 7

\[\frac{ 1+\sin \theta-\cos^{2}\theta }{ 1+\sin \theta }=\frac{ 1+\sin \theta-1+\sin^{2}\theta }{1+\sin \theta }=\frac{ \sin \theta+\sin^{2}\theta}{ 1+\sin \theta }=\sin \theta \]
