Question

minimum value of cos x​

Answer 1

Answer:

The minimum value of cos(cosx)is cos1. Note: Cosine is a decreasing function. It has maximum value 1 when x=0∘ and minimum value 0 when x=π2. So we can also say cos(cosx)will have maximum value when cos(x) has minimum value i.e 0 and vice versa.
