Step-by-step explanation:
In general, you can skip the multiplication sign, so 5x is equivalent to 5⋅x.
In general, you can skip parentheses, but be very careful: e^3x is e3x, and e^(3x) is e3x.
Also, be careful when you write fractions: 1/x^2 ln(x) is 1x2ln(x), and 1/(x^2 ln(x)) is 1x2ln(x).
If you skip parentheses or a multiplication sign, type at least a whitespace, i.e. write sin x (or even better sin(x)) instead of sinx.
Sometimes I see expressions like tan^2xsec^3x: this will be parsed as tan2⋅3(xsec(x)). To get tan2(x)sec3(x), use parentheses: tan^2(x)sec^3(x).
Similarly, tanxsec^3x will be parsed as tan(xsec3(x)). To get tan(x)sec3(x), use parentheses: tan(x)sec^3(x).
From the table below, you can notice that sech is not supported, but you can still enter it using the identity sech(x)=1cosh(x).
If you get an error, double-check your expression, add parentheses and multiplication signs where needed, and consult the table below.
