Hey!
I'm having a little problem with a program I'm trying to write in Dr Scheme
I wrote
(define (vectornorm t n s)
(sqrt (+ (expt t 2) (expt n 2) (expt s 2)) 1/2))
But it gives error in the square root part. Can anyone help me?

im sure you've already figured this out by now, really simple mistake. but just in case: sqrt takes 1 argument. seems to me that you meant to do (expt value1 1/2) to do the sqrt for you.
the fix is obvious, but im gonna post this to see if the forum does syntax highlighting for scheme
also, i dont know if you had completed the function yet, but your code seems to produce the magnitude rather than a normalized vector

you're right. when i looked at it again i found my mistake immediately, but thanks anyway!
