I have 2 questions to ask.

Which is “integrand” and the “antiderivative” on the attached image?

What is “hyperbolicus” (form of trigonometry identities which include e or exponential)?

I am an undergraduate student of engineering, so please tell me the easiest simplest way on this. I see many people here are advance.

Thank you

I'm going to ask what do you think corresponds to each of the terms from the image just in case this is a homework question. Just to define some terms however, the integrand is the function being integrated and the antiderivative is a function whose derivative is the integrand.

By "hyperbolicus" do you mean what in English are called the "hyperbolic functions"?

The answer to one part is correctly answered by kurdt.Hyperbolis are the hyperbolic functions that take into account the imaginary cases also.More read with the help of google as I am not able to write the expressions here.
