Question

If x=3 sin2

, y=3cos2 +1, then find x+y.​

Answer 1

Answer:

X + Y = 4

Step-by-step explanation:

X = 3 sin²∅

Y = 3 cos²∅ + 1

X + Y = 3 ( sin²∅ + cos²∅ ) + 1

X + Y = 3 + 1 = 4

Answer 2

Answer:

Ans:4

Step-by-step explanation:

x=3 sin²Ф

, y=3cos²Ф +1

x+y=3 sin²Ф+3 cos²Ф+1

=3*( sin²Ф+ cos²Ф)+1

=3+1=4
