Evaluate the following integral.

{eq}\displaystyle \int e^x \cosh x \ dx {/eq}

Question:

Evaluate the following integral.

{eq}\displaystyle \int e^x \cosh x \ dx {/eq}

Cosine Hyperbolic Function as Integrand:

The cosine hyperbolic function is defined as the ratio of the sum of exponential functions {eq}e^x {/eq} and {eq}e^{-x} {/eq} over the integer value {eq}2 {/eq}. The product rule of exponential expression for the simplification of the integral expression is:

{eq}e^a\cdot e^b=e^{a+b} {/eq}
