expand (e^{k(t-a)}-1)/(e^{k(t-a))+1}

expand

\frac{e ^{k (t - a)} - 1}{e ^{k (t - a)} + 1}

\frac{e ^{k t - ak} - 1}{e ^{k t - ak} + 1}

Solution steps

\frac{e ^{k (t - a)} - 1}{e ^{k (t - a)} + 1}

Expand

k (t - a) : k t - ak

= \frac{e ^{k (t - a)} - 1}{e ^{k t - ak} + 1}

Expand

k (t - a) : k t - ak

= \frac{e ^{k t - ak} - 1}{e ^{k t - ak} + 1}
