Question

The minimum value of sin theta + root 3 cos theta is

Answer 1

Answer:

2

Explanation:

for minimum value differentiate the above give ram w.r.t theta

Equate the equation to zero. Angle comes out to be 30 degree .

Put the value hence answer will be 2

Answer 2

Answer: -      -2

Explanation:  we use the formula for the type
a sin θ ± b cos θ =  ±√(a^2 + b^2 ) { for min. use – , for max. use + }

thus: $-\sqrt{1^2+\sqrt{3}^2 }$= -2
