Homework Help: Finding The min Value

  1. Jan 7, 2012 #1
    Find where the min value will occur of tan(x^2+2x)

    is there a way to do this without a calculator because I can't seem to figure it out with out it. Also I'm not sure what the interval should be.

    There's always Calculus!

    What's the derivative of tan(x2+2x) ?

    BTW: There is no absolute minimum.

    There is one relative minimum which can be easily found using the derivative.

    sec^2(x^2+2x)*(2x+2).... I got it now. Thanks, I was messing up my line check.
