To integrate ( \int 2^{\sin x \cos x} ,dx ), we can use a substitution method, but this specific integral does not result in a simple form using elementary functions. There isn't a straightforward substitution or technique that simplifies this to a form that can be easily integrated with basic calculus methods. The integration of functions like (2^{\sin x \cos x}) often involves complex or special functions and sometimes may not have a closedform solution expressible in terms of elementary functions.
For educational purposes, let's outline a general approach one might consider for tackling an integral that doesn't readily simplify:

Look for Symmetry: This is useful for definite integrals over symmetric intervals. For this specific function, symmetry might not simplify the integral, but it's a good habit when approaching integration.

Substitution: Identify substitutions that might simplify the integrand. For (2^{\sin x \cos x}), typical substitutions like (u = \sin x) or (u = \cos x) don't directly simplify the exponentiation.

Series Expansion: One advanced method is to expand (2^{\sin x \cos x}) using a series (e.g., Taylor or Fourier series) and then integrate term by term. This approach can be mathematically intensive and may not lead to a simple form.

Numerical Integration: When a function doesn't have a neat antiderivative, numerical methods (e.g., Simpson's rule, trapezoidal rule) can be used to estimate the integral's value over a specific interval.

Special Functions: Occasionally, integrals lead to special functions not part of the standard calculus curriculum, such as Bessel functions or elliptic integrals.
For ( \int 2^{\sin x \cos x} ,dx ), without specific bounds, you're likely looking at a situation where numerical methods or series expansion provide the best path forward for approximation rather than finding a closedform solution.

When evaluating a onesided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
