    Finding the area of a region bounded by curves or lines

    Please see the attached file for the fully formatted problems. Find any relative extrema and inflection points of the function y= x a. y = x2 ln x dy/dx = To find teh relative extrema, we set dy/dx = 0 Or x(1 + 2ln x) = 0 Or x = 0, because ln cannot go into the negative. Clearly, x = 0 is a point of inflection

    Evaluating Definite Integrals

    Finding Integrals

    ∫3xe^(x^2 + 7) dx See attached file for full problem description.

    Using Shell Method to Evaluate Integrals

    Use the shell method to set up and evaluate the integral that gives the volume of the solid generated by revolving the plane region about the x-axis: y=x^3, x=0, y=8

    Finding an Integral for the Positive Sense of a Circle

    a) Compute the integral of xdz (|z|=r) for the positive sense of the circle in two ways first by using parametrization and second by observing that x=(1/2)(z+z conjugate)=(1/2)(z+r^2/z) on the circle. b) Compute the integral of dz/(z^2-1) (|z|=2) for the positive sense of the circle. PS - Here maybe we have to find first a p

    Finding the Definite Integral

    (See attached file for full problem description) Find the definite integral __ ∫-18 3√x dx Note - The 8 is supposed to be directly over the -1.

    determine the cost function by integral

    Determine the cost function C(x) that corresponds to the marginal cost and fixed cost given. Marginal cost = 30 - 0.05x, Fixed cost = $100 (See attached file for full problem description)

    Numerical Integration, Trapezium Rule, Error bound formula,

    It is required to use the Trapezium's rule to evaluate the integral of sin(x)^2 from 0 to pi/2 to four decimal place accuracy. Use the error bound formula to recommend the number of panels n. Find the Trapezium rule approximation of the integral with n=2 and compare with the exact value. Does this result contradict your part
