To get `tan^2(x)sec^3(x)`, use parentheses: tan^2(x)sec^3(x). Evaluating Functions Evaluating Functions. From the table below, you can notice that sech is not supported, but you can still enter it using the identity `sech(x)=1/cosh(x)`. Sometimes I see expressions like tan^2xsec^3x: this will be parsed as `tan^(2*3)(x sec(x))`. Function Evaluation Calculator. Also, be careful when you write fractions: 1/x^2 ln(x) is `1/x^2 ln(x)`, and 1/(x^2 ln(x)) is `1/(x^2 ln(x))`.
