Arduino Math Continued (pythagorean theorum)

#include "math.h" // include the Math Library

int a = 3;
int b = 9;
int h;

void setup() // run once, when the sketch starts
{
Serial.begin(9600); // set up Serial library at 9600 bps

Serial.println("Lets calculate a hypoteneuse");

Serial.print("a = ");
Serial.println(a);

Serial.print("b = ");
Serial.println(b);

h = sqrt( a*a + b*b );

Serial.print("h = ")
Serial.println(h);
}

void loop() // we need this to be here even though its empty
{
}

This is a nifty little program where you enter the length of the legs on the triangle, and the Arduino will calculate its hypotenuse.
