Question

if sin theta +sin²theta =1 find cos²theta+cos⁴theta​

Answer 1

Answer:

➡️

$sin θ+sin² θ=1(given)$

$\sinθ = { \cos} \ ^{2} θ$

$cos²θ+cos⁴θ = \sinθ + { \sin }^{2} θ$

$as \: per \: given \: value \: is1$

So your answer is 1.✅

Answer 2

Answer:

sin θ+sin² θ=1(given)

\sinθ = { \cos} \ ^{2} θsinθ=cos 2θ

cos²θ+cos⁴θ = \sinθ + { \sin }^{2} θcos²θ+cos⁴θ=sinθ+sin2θ
