- If a functionfis increasing on (a,b) and decreasing on (b,c) , then what can be said about the local extremum offon (a,c) ?Assume that f : (0, 1) → R is a differentiable function with the derivative f' increasing on (0, 1). Prove that f' is continuous on (0, 1).Let f(t) = et^2 be an integrable function defined on the closed interval [-x, x] on ℝ. If F is the anti-derivative of f on [-x, x], prove that F'(x) = f(x) for all x in [-x, x].
- Show that f(z) =xy+iy is everywhere continuous but is not analyticLet ƒ(x, y) =(x2-y2)/(x2+y2) for(x, y) ≠ (0, 0). Is it possible to define ƒ(0, 0) in a way that makes ƒ continuous at the origin? WhyAssume the second derivatives of ƒ are continuous throughout the xy-plane and ƒx(0, 0) = ƒy(0, 0) = 0. Use the given information and the Second Derivative Test to determine whether ƒ has a local minimum, a local maximum, or a saddle point at (0, 0), or state that the test is inconclusive. ƒxx(0, 0) = -9, ƒyy(0, 0) = -4, and ƒxy(0, 0) = -6
- Consider the function f defined on [0,∞), f(x)=(x^r)sin(1/x), for x≠0 and f(x)= 0, where r>0. Determine the range of r in which a) f is continuous on [0,∞), b) f is differentiable on [0,∞), c) f' exits and is differentiable on [0,∞).Show that f(x,y)=exyx is differentiable at point (1,0) using the definition of differentiability.Let f(x, y) = { cosy. sinx, x ≠ 0cosy, x = 0Is f continuous at (0,0)? Is f continuous everywhere?
- Suppose that a nonnegativefunction y = ƒ(x) has a continuous first derivative on [a, b] . LetC be the boundary of the region in the xy-plane that is bounded below by the x-axis, above by the graph of ƒ, and on the sides by the lines x = a and x = b. Show that ∫ƒ(x) dx = - ∮C y dx.Let f(x, y) = x2y4 sin(1/ (sqrt(x2+y2)) where (x, y) cannot be (0, 0) and f(0, 0) = 0 Is f continuous in origo?Suppose that a differentiable function ƒ(x, y) has the constant value c along the differentiable curve x = g(t), y = h(t); that is, ƒ(g(t), h(t)) = c for all values of t. Differentiate both sides of this equation with respect to t to show that ∇ƒ is orthogonal to the curve’s tangent vector at every point on the curve.
