Amplitude[x_] := 1/2^0.5 (FresnelC[x + 0.645] - FresnelC[x - 0.645] + i (FresnelS[x + 0.645] - FresnelS[x - 0.645])) y[x_] := (Abs[Amplitude[x]])^2 Plot[y[x], {x, -10, 10}]
This is my input. Please can you find any mistakes in this
Hi Cameron,
just write for the imaginary unit I instead of i. Names of build in functions and constants always begin with a capital letter. For the same reason you should name own functions e.g. amplitude[] instead of Amplitude[].
I
i
amplitude[]
Amplitude[]

I've managed to get it to work now, thank you
