Unformatted text preview: -. x^2/3 and x^(2/3) are different. Use parentheses liberally to avoid ambiguity and errors. Functions Square root: either sqrt(x) or x^(1/2) are OK. e x is exp(x) ln( x ) is log(x) or ln(x) log 10 ( x ) is log10(x) Trigonometric Functions Note that angles are always given in radians! sin( x ) is sin(x) , etc. sin-1 ( x ) is asin(x) , etc. tan-1 ( y/x ) can also be written as atan2(x,y) , etc. This form is superior when there can be a question of quadrants....
