Question

the value of x for the minimum value of 3 cos theta +sin theta is
​

Answer 1

Answer:

x = 90

Step-by-step explanation:

3 cosx + sinx

We need to keep cosx as low value because it is getting multiplied by 3. Lowest value of cosx should be 0. Take x as 90 because cos90 = 0

3 * cos90 + sin90

= 3 x 0 + 1

= 1
