Question

Find the absolute maximum value and the absolute minimum value of the following functions in the given intervals:
f (x) = sin x + cos x, x ∈ [0, π]

Answer 1

Differentiate the given function f (x) = sin x + cos x f' (x) = cos x - sin x Put f' (x) = 0 , cos x - sin x = 0 cos x = sin x tan x = 1 x = tan- ... pls Mark brainliast
