Find the minimum value of the function
`f(x)=(1+sinx)(1+cosx),AAx inR`.

A

A. 0

B

B. - 1

C

C. - 2

D

D. None of These

Text Solution

Verified by Experts

The correct Answer is:
0
Since `0le1+sinxle2" and "0le+cosxle2`,
minium value of f(x) is 0, when any one of `(1+sinx)" or "(1+cosx)` is zero.
