    :!) :smile: This question simply says [SIZE="4"]calculate Question [integral from 0 to t]xe^-xdx this is one of the questions from my calculus online course there are no similar examples to this in the given notebookk i have taken the first year calculus but forgot somestuff, this was 3...

    Integrating Sin^2[x] from 0 to t: Solve with Identity

    Ok i think i got it:shy: I just one clerification is sin^2[x] the same as Sin[x]^2?

    Integrating Sin^2[x] from 0 to t: Solve with Identity

    back to the integration problem the substitution was the first thing i did i should leave the sin[x]^2 like it is then?? let sin[x]= u ? what is the integral of Cos[2x]?? please

    Integrating Sin^2[x] from 0 to t: Solve with Identity

    [SIZE="5"]Use the identity Sin[x]^2 = [1-Cos[2x]]/2 to help calculate integral from 0 to t Sin[x]^2 dxThis question seems really easy but I am having some difficulty with it. This is what I am thinking : first put the [1-Cos[2x]]/2 instead of the Sin[x]^2 so this is what i have now (int...
