f(x) = e x . cos x, x ∈ ∈ [0, 2 π π ]. The slope of tangent of the function is minimum for
Text Solution
Verified by ExpertsThe correct answer is:
A
f(x) = e x cosx
⇒ ⇒ f '(x) = e x (cosx − − sinx)
⇒ ⇒ f "(x) = e x ( − − 2 sinx)
Sign scheme of f"(x) is,
That mean x = π π is the point of minima of f '(x).
