    Fundamental Theorem of Calculus Problem

    I SOLVED IT! Thank you so much, mfb and Mark44! I didn't know that I had to find the derivative for xlnx! Thank you, thank you, thank you!

    Fundamental Theorem of Calculus Problem

    I'm going to type out my work, okay? Can you check my work and see if I am doing it correctly? u = x^2 --> sqrt(u) = x g'(x) = ∫ u*lnu with sqrt(u) being the upper limit and 0 being lower Am I doing it correctly?

    Fundamental Theorem of Calculus Problem

    1. If g(x) = ∫ f(t) dt = xln x, find f(1) The ∫ has x^2 on top and 0 on bottom. 2. g'(x) = f(x) <--FTC1 The Attempt at a Solution g'(x) = f(x) u=x^2 g'(x) = u*lnu * 2x(derivative of inner function) g'(x) = 2x(x^2)ln(x^2) f(1) = 2(1)(1^2)ln(1^2) f(1) = 0, since ln(1) = 0 I...
