Question

if cos theta + cos² theta = 1 then sin² theta + sin⁴ theta =



don't answer directly pls
post the method too​

Answer 1

Answer:

ez cos teta + cos^2theta = 1

cos theta = 1- cos ^theta

costheta= sin^2 theta

now in eq two

costheta + cos ^2 theta = 1 ( subtituting above value )

1 is the answer
