Question

if x= 2 sin square theta and y = 2 cos square theta, then find X+Y​

Answer 1

Step-by-step explanation:

Given, x=2sin

2

θ,y=2cos

2

θ+1

To find: (x+y)

x+y=2sin

2

θ+2cos

2

θ+1

=2(sin

2

θ+cos

2

θ)+1 .....(As sin

2

θ+cos

2

θ=1)

=2+1

=3

Answer 2

Answer:

x= 2 sin²thita

y= 2cos² thita

Now to find x+y

2 sin²thita + 2 cos²thita

2( sin²thita+cos²thita)

As we know that sin² thita + cos² thita =1

So put the value

2×1

2

Answer = 2
