Question

if x=2sin^2 O and you=2cos^2 O=then find the value of x+y
.​

Answer 1

2

Step-by-step explanation:

x = 2sin^2A ,y = 2cos^2A

x+y = 2sin^2A + 2cos^2A

= 2(sin^2A+ cos^2A) = 2 × 1 = 2

Answer 2

Answer:

2

Step-by-step explanation:

$\sf We \: have,$

• $\sf x=2 \sin ^2 θ$
• $\sf y=2 \cos ^2 θ$

$\sf \blue{x+y}=2 \sin ^2 θ+2 \cos ^2 θ$

$\sf : \implies 2 \sin ^2 θ+2 \cos ^2 θ$

$\sf : \implies 2 (\sin ^2 θ+ \cos ^2 θ)$

We know that,

$\red{\underline{\boxed{\sf \sin ^2 θ+ \cos ^2 θ=1}}}$

$\sf : \implies 2 (1)=2$

$\sf \blue{x+y} = \blue{2}$
