v7 v8 10 10 with the inverse 11 11 12 [[latex($ \Xi[F]^{-1} = f(x) = \int^{+\infty}_{-\infty} F(k)) e^{(i 2 \pi k x)} dk $)]] 12 [[latex($ \Xi[F]^{-1} = f(x) = \int^{+\infty}_{-\infty} F(k)) e^{(i 2 \pi k x)} dk $)]] 13 14 And of course all the transform really means is this sum of intergrals. 15 16 [[latex($ F(k) = \int^{+\infty}_{-\infty} f(x) cos(2\pi kx) dx - i\int^{+\infty}_{-\infty} f(x) sin(2\pi kx) dx $)]] 13 17 14 18 Here we want to solve the signup function which is runs from -1 to 1 with a step at x=a
