Reduce each of the following expressions...

Reduce each of the following expressions to the sine and cosine of a single expression: `24 costheta+7s intheta`

Text Solution

Verified by Experts

We know that the maximum and minimum values of `acosx+bsinx `are `sqrt(a^2+b^2)` ​ and `−sqrt(a^2+b^2)` ​
Hence, the maximum and minimum values of `7sintheta+24costheta `are `sqrt(7^2+24^2) ​=25 `
and `−sqrt(7^2+24^2) ​=−25`.
