If x=2 sin square than tithe y =2 cos square than tithe ,then find x+y​

Answer 1

$\LARGE{\bf{\underline{\underline{\black{GIVEN:-}}}}}$

• $\sf x=2sin^2\theta$

• $\sf y=2cos^2 \theta$

$\LARGE{\bf{\underline{\underline{\black{TO:FIND:-}}}}}$

• x+y=?

$\LARGE{\bf{\underline{\underline{\black{SOLUTION:-}}}}}$

$\to \sf x+y$

Substitute the values.

$\to \sf 2sin^2\theta+2cos^2\theta$

Take "2" common.

$\to \sf 2(sin^2\theta+cos^2\theta)$

We know that sin²θ+cos²θ=1. Thus, substitute.

$\to \sf 2(1)$

$\boxed{\sf{\blue{2}}}$

∴x+y=2.
