Hi,

I am trying to find out why this function is not working:

<?php
$b = $_GET['b'];
$c = $_GET['c'];

function someFunc($a, $b, $c){
if (!is_numeric($a)){
$result = sqrt (pow($c, 2)-pow($b, 2));
	}
return $result;
}
?>

 

I keep getting the wrong values when i give it some numbers...like when i ask for sqrt of 36+24, it gives me a value of 60 instead of something like 7......?

Errrrr...

 

I'm sure it's returning what you're telling it to.

 

srqt(c^2 - b^2)

 

 

And it seems to me that you want sqrt(c-b)?

hmm c^2 - b^2 that's what i want it to return, but instead it outputs something completely different lol...

Specifics:

What are the values of $b and $c that you're passing to the function? What are you getting back? And what do you expect to get back?
