    MHB Integrating $\cos(mx)$ with Two Variables

    $$\int x^2\cos(mx)\,dx$$ When integrating this by parts, the $x^2$ will become the $u$ and the $\cos(mx)\,dx$ will become $dv$. How is the $\cos(mx)$ integrated if there are two variables?

    MHB Why is my teacher calling 2m+(50s)(0.5m/s) pure piffle?

    oh... haha thank you!

    MHB Why is my teacher calling 2m+(50s)(0.5m/s) pure piffle?

    2m+(50s)(0.5m/s) = 2m + 25m/{s}^{2} = Not possible My teacher keeps saying this is pure piffle and shaking his head. Can someone please explain this to me?

    MHB Limit of e to the tangent of x

    lim {e}^{tan(x)} x\implies\{(pi/2)}^{+} How do I start? Do I plug in and if so what next?
