Another problem

  1. Apr 25, 2006 #1
    Find an equation of the curve that satisfies

    dy/dx = 88yx^(10)
    and whose y intercept is 4

    dy/y = 88x^(10)dx

    integral both sides

    ln(y) = 8x^(11)
    y = e^(8x^(11))+C

    put x = 0 into the equation
    I got C = 3.

    Why am I wrong?

    Because you're supposed to add the constant of integration C right after you integrate, and THEN exponentiate both sides.
