Question

sin^(2) 45+cos^(2) 60=1

Answer 1

hiii!!! folk.

it's too easy ....

from lhs

as you know that sin45°=1/√2 and cos60°=1/2

so,
=)sin^2 45°+cos^2 60°

=)(1/√2)+(1/2)^2

=)1/2+1/4

=)2+1/4

=)3/4........
hey your question is wrong.......

sin^245°+cos^260°=1 never ..
.
hope it help you.

Answer 2

Hey there!!

Thank u for your Question ,

Here

we have ,

${ \sin}^{2}45 + { \cos }^{2} 60 \\ \\ = > ( { \frac{1}{ \sqrt{2} }) }^{2} + { (\frac{1}{2} )}^{2} \\ \\ = > \frac{1}{2} + \frac{1}{4} \\ \\ = > \frac{3}{4}$
Here LHS is not equal to RHS

therefore

it is wrong

Hope this helps u!!
