Question

find the minimum and maximum values of f(x)=7cosx-24sinx+5​

Answer 1

Answer:

Step-by-step explanation:

If we see any function of the form

a sinx + b cos x or a sinx- b cosx

Its maximum value is

(a²+b²)

& its minimum value is

(a²+b²)

Hence maximum value of the above function is

(24²+ 7²)  +5 = 25 +5 = 30

& Its minimum value is

-25 +5 = -20
