The minimum value of both sine and cosine is -1. However the angles that produce the minimum values are different,
for sine and cosine respectively.
The question is, can we find an angle for which the sum of sine and cosine of such angle is less than the sum of values at any other angle.
Here is a procedure, first take a derivative
![\frac{d}{dx}(\sin x+\cos x)=\cos x -\sin x](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7Bdx%7D%28%5Csin%20x%2B%5Ccos%20x%29%3D%5Ccos%20x%20-%5Csin%20x)
Then compute critical points of a derivative
.
Then evaluate
at
.
You will obtain global maxima and global minima
respectively.
The answer is
.
Hope this helps.

Answer:
9 degrees
Step-by-step explanation:
given:
Initial temperature : 17 degrees
temperature change = reduction by 8 degrees (i.e - 8 degrees)
hence the final temperature
= initial temperature + temperature change
= 17 + (-8)
= 17 - 8
= 9 degrees
