Integration for beginners watch

    • Thread Starter

    Hi, I am trying to solve a problem for a maths coursework and I am trying an alternative approach. I have gathered from some other sources I might need something called integration.

    I have f''(x) = (x-0)(x-p)

    I need to obtain a quartic function from that somehow... Is there a way to do this?

    f''(x) = (x-0)(x-p) = (x)(x-p) = x^2 - px

    ok. the fundamental theorem of calculus defines integration as geing the invert of differentiation. So, we 'reverse differentiate' twice to find f(x).

    given dy/dx = nmx^n-1 for y=mx^n, it should eb clear the integral of mx^n is (mx^(n+1))/(n+1) + c. the c denotes some constant which would have been gotten rid of by the differentiation process. so,w e apply this twice tog et to f(x):

    f''(x) = x^2 - px

    f'(x) = (x^3)/3 - (px^2)/2 + c

    f(x) = (x^4)/12 - (px^3)/6 + cx + k
