Question

trigonometry proof question​

Answer 1

Answer:

answer is 1, the solution is as follows kindly mention the 'given' and 'to find' in your answer

Answer 2

$\sin(theta) + \sin^{2} (theta) = 1$

$1 = \sin^{2} (theta) + \cos^{2} (theta)$

therefore

$\sin(theta) + \sin^{2} (theta) = \sin^{2} (theta) + \cos^{2} (theta)$

Eliminating sin2 theta from both sides

$\sin(theta) = \cos^{2} (theta)$

put this into the first equation and you will get

$\sin(theta) + \sin^{2} (theta) = 1$

$\cos ^{2} (theta) + \cos^{4} (theta) = 1$

Answer is 1
