$$ \int_{-2} \frac{e^{17z}}{e^{17z}+1} dz $$ $$ u = e^{17z}+1 $$ $$ du = e^{17z} \cdot 17 dz $$ $$ \frac{1}{17} du = e^{17z} dz $$ $$ = \int \frac{\frac{1}{17} du}{u} $$ $$ = \frac{1}{17} \int_{e^{-34}+1}^{e^{34}+1} \frac{du}{u} $$ $$ = \frac{1}{17} \ln|u| \Big|_{e^{-34}+1}^{e^{34}+1} $$ $$ = \frac{1}{17} (\ln(e^{34}+1) - \ln(e^{-34}+1)) $$
