Question

The function f(x,y) = R x y cos(t²)dt has exactly one critical point in the domain 0 < x < 2, 0 < y < 2. Find this critical point and determine whether it gives a relative maximum, minimum or saddle point for this funciton.

2. The function f (r, y) = S" cos(t²)dt has exactly one critical point in the domain 0 <
x < 2,0 < y < 2. Find this critical point and determine whether it gives a relative
maximum, minimum or saddle point for the function.

Formula Formula A function f(x) attains a local maximum at x=a , if there exists a neighborhood (a−δ,a+δ) of a such that, f(x)<f(a), ∀ x∈(a−δ,a+δ),x≠a f(x)−f(a)<0, ∀ x∈(a−δ,a+δ),x≠a In such case, f(a) attains a local maximum value f(x) at x=a .
