Question

Cos square alpha+sin square alpha is equal to

Answer 1

Answer:

cos^2(x)+sin^2(x)=1

Step-by-step explanation:

we have an identity that is

sin^2(x)+cos^2(x)=1

so answer is 1

Answer 2

Answer :

➺ Cos²α + Sin²α = 1 because it is a identity used in the trigonometry.

$\rule{200}{2}$

There are sum another identities of chapter Trigonometry  ⤵⤵⤵

(i) Sin (90° - θ) = Cos θ

(ii) Cos (90° - θ) = Sin θ

(iii) tan (90° - θ) = Cot θ

(iv) Cot (90° - θ) = tan θ

(v) Sec (90° - θ) = Cosec θ

(vi) Cosec (90° - θ) = Sec θ

(vii) Sin²θ + Cos²θ = 1

(viii) 1 + tan²θ = sec²θ

(ix) 1 + Cot²θ = Cosec²θ
