Find the antiderivative

So to account for this potential loss, you would just add C.......
of ∫ (e^t + 1/t)dt

To take the integration of e^t, you have to take the dirivative of it's exponent and multiply it to the original equation.

int.] e^t = 1 * e^t (as d/dt (t) = 1)

Next, there is a formula that states the integral of 1/x is ln x.

int.] 1/t = ln (t)

Lastly, whenever you do an integral you also must take into account the the antiderivative could have had a constant (as the derivative of a constant is zero). So to account for this potential loss, you would just add C. So your answer is

e^(t) + ln (t) + C

-
As given MUST be read as :-
I = ∫ e^t + (1/t) dt
I = e^t + ln t + C

-
= e^(t) + ln|t| + C

-
e^t + Log[t]
