    This is a asymptotic problem

    Homework Statement Find the complete asymptotic expansion of the function \sqrt{1+x^{6}} - x^{3}lnx as x\rightarrow\infty and x\rightarrow0. In each case give the asymptotic sequence in decreasing orders of magnitude. Homework Equations I tried the Taylor Expansion about 0. But I don't...

    Change the integral limit

    Homework Statement \int^{2\pi}_{0}cos^{2}(\theta)sin^{2}(\theta)cos(\theta)sin(\theta)d\theta If I set x=cos^{2}(\theta), the integral limit should be from 1 to 0 or need I break this integral into to 4 parts (i.e from 1 to 0 plus from 0 to 1 plus from 1 to 0 plus from 0 to 1)? Homework...

    A pendulum oscillation problem

    Homework Statement Consider a pendulum oscillation problem, where pendulum oscillates around the vertical in the downward configuration. Assume that there is no friction at the pivot point around which the pendulum rotates, and assume that there exists a torsional spring that counter acts...
