Power & Summation Rules

  1. Jun 12, 2004 #1
    Is this simplified?

    Use the power rule and the summation rule to find f ' (x) and simplify where possible

    f(x) = ((2x^3)/5) - x^2 +3/8

    f ' (x) = d/dt(((2x^3)/5) - x^2 +3/8) = ((6x^2)/5) - 2x

    Is this the right answer?

    Except, it should be d/dx...not d/dt !
