Y =2/(sinθ + √3cosθ)

for solving this question, you should understand one thing 

- ≤ asinx + bcosx ≤

So, -√(1 + √3²) ≤ (sinθ + √3cosθ) ≤ √(1 + √3²)

-2 ≤ (sinθ + √3cosθ) ≤ 2 

So, minimum value of (sinθ + √3cosθ) = -2 

Maximum value of (sinθ + √3cosθ) = 2 

For getting minimum value of y , we have to use maximum value of (sinθ + √3cosθ) .

So, minimum value of y = 2/-2 = 1 

Hence, =1

Answer 2

Answer:

hello I hope this helps you

Explanation:

if y =2 sin theta

route 3 cos theta

then the maximum value of Y is =2+3 or 3-2

.'. 5 or 1

final answer is 1/5
