This question already has an answer here:
- How to plot imaginary part of a function 3 answers
I used free-from input to do this:
= integrate sec x with respect to x
I got a huge amount of information, but I'd like to focus on this plot that was given:
Can my colleagues show how to do this plot?
It's also interesting that Mathematica gives this answer:
In:= Integrate[Sec[x], x]
Out= -Log[Cos[x/2] - Sin[x/2]] + Log[Cos[x/2] + Sin[x/2]]
But if we click on Step-by-step-solutions, Wolfram Alpha gives this answer:
Which is similar to the hand-calculated solution
$$\ln|\sec x+\tan x|+C$$
