Proof of cos^2 theta + sin^2 theta = 1

Why does sine squared plus cosine squared equal 1?

sin square theta + cos square theta = 1 How to prove?

sin^2 θ+ cos^2 θ =1 | 1+ tan^2 θ =sec^2 θ | 1+cot^2 θ =cosec^2 θ Prove Trigonometric Identities

1+cosx=2cos^2(x/2) trigonometry identites solve || 1+cos(theta)

( 1/1+cos theta ) + (1/1-cos theta)=2 cosec^2 theta

`(tan^2 theta)/((sec theta-1)^2)=(1+cos theta)/(1-cos theta)`
