Question

${e}^{ - a} - {e}^{a }$
​

Answer 1

Step-by-step explanation:

$\implies {e}^{ - a} - {e}^{a} \\ \implies \frac{1}{ {e}^{a} } - {e}^{a} \\ \implies \frac{1 - {e}^{ {a}^{2} } }{ {e}^{a} } \\ \implies \huge \boxed{ \frac{1 - {e}^{2a} }{ {e}^{a} } }$

Answer 2

Hello....

.

$e {}^{ - a} - e {}^{a} \\ \frac{1}{e {}^{a} } - e {}^{a} \\ = \frac{1 - e {}^{2a} }{e \frac{a}{} } \\ hope \: its \: helps....$
