Your parentheses are wrong. Change pow(( to pow(.

In function 'void loop()': error: too few arguments to function 'double pow(double, double)' GettingValues:41: error: at this point in file error: too many arguments to function 'double square(double)' GettingValues:42: error: at this point in file error: too many arguments to function 'double square(double)' | |

pow(x, 2) is the second power, so x² or x*x. sqrt(x) is the square root of x, so $\sqrt x$. A whole circle is 360 degrees or 2π when measuring in radians. So this ratio of 180/3.141592 is used to convert an angle in radians to an angle in degrees.
