    Problem simplifying v*dv/dt to get d/dt(V^2/2)

    Thank you very much pengwuino. I would never have thought of that.

    Integral of an exponential function

    I was actually thinking: you perform integration by parts once to reduce t^2 to t. Result is that one of the terms is integral((e^-t)/t) Rewrite that term to become integral(1/te^t) use the following identity from integral tables: integral(ue^u) = (u-1)e^u the rest is taking limits.

    Integral of an exponential function

    You can use integration by parts. Using u = e^-t and dv = t^-2 dt

    Problem simplifying v*dv/dt to get d/dt(V^2/2)

    Homework Statement we know dV/dt = a from the definition of acceleration multiplying by sides by V, velocity yields V dV/dt = aV Left side can be reduced to d/dt(V^2/2) so to be more clear, just looking at the left side V dV/dt = d/dt( V^2/2) I want to know what calculus topic...
