The expression you provided is:

$e^x - 4 \ln(\cos(x))$

To analyze or differentiate it further, we can break it down into two main parts:

1. $e^x$, the exponential function.
2. $-4 \ln(\cos(x))$, where $\ln$ is the natural logarithm of $\cos(x)$.

Would you like me to simplify, differentiate, or provide more details about this expression?
