Question

What is e(exponential) term in intigration?

Answer 1

`e` by itself is a constant. If it has an exponent with a variable, it is a function.

Explanation:

If you see it as something like `int_` `e^(2+3) dx` it will just be equal to `e^5x + C`. If you see it as `int_` `e dx` it will be equal to `ex + C`.

However, if we have something like `int_` `e^x dx` it will follow the rule of `int_e^(k*x)dx = 1/k*e^(kx)+C`. Or in our case `int_e^(1*x) dx = 1/1e^(1*x)+C=e^x+C`.
