Find the maximum and minimum values of `7\ costheta+24 s intheta`

Explanation

We know that the maximum and minimum values of `acosx+bsinx `are` sqrt(a^2+b^2)`
​ and` -sqrt(a^2+b^2)`
​ respectively.


Hence, the maximum and minimum values of `7cosx+24sinx` are `sqrt(7^2+24^2)

​=25 `

and` −sqrt(7^2+24^2)​=−25`
respectively.
