Root and Logaritmic Functions

function name examples remarks
ln natural logarithm function ln(2^x), ln(e^x), ln(x+1), log(log(x))
log general logarithm function log(x), log(log(x)), log(x,x) Works with either 1 parameter or two. If only one parameter is used the function is same as ln, with base e (e.g. log(1/x)). If two variables are used, the second variable is used to specify the base of the logarithm (e.g. base 2 is log(x,2))
sqrt square root sqrt(x), sqrt(cos(x)), sqrt(sin(x)), sqrt(ln(x))
