Question

If x=asin²θ,y=acos²θ then x+y=​

Answer 1

Answer:

x+y =a

Step-by-step explanation:

$x+y = acos^{2}\alpha + asin^{2}\alpha \\=a(cos^{2}\alpha + sin^{2}\alpha)\\=a(1)\\=a$

Answer 2

Step-by-step explanation:

x=asin^2theetha

y=acos^2theetha

x+y=?(to be calculated)

asin^2theetha +acos^2theetha =1

(using identity = sin^2theetha +cos^2theetha =1).
