How to do a taylor series in matlab with e?

if the equation was g(x)=e^x/(cos(x)+tan3(x)) for x=2 I tried >> x=2;taylor(exp(e^x/(cos(x)+tan3(x)))) but an error comes up with undefined function or variable 'e'

Check out this example of how to compute Taylor series in Matlab:

Make sure you define x as a symbolic variable first.

now it says undefined function 'taylor'

taylor operates symbolically

You need to give it the variable.

Do you have the symbolic math toolbox?
