Write the maximum and minimum values of ...

Write the maximum and minimum values of `3cos x+4sin x+5.`

Text Solution

Verified by Experts

Given,
`3 cos theta + 4 sin theta + 5`
The maximum value of `a cos theta + b sin theta + c` is `c + sqrt((a^2 + b^2))`
Substituting `a = 3, b = 4, c = 5`
`c + sqrt((a^2 + b^2))`
...
