Okay, then what is the integral of e^xcos(x)?

The integral of e^x cos(x) cannot be solved using elementary functions. However, it has a solution using special functions called the exponential integral or the Fresnel integral.

The exponential integral is defined as follows:

∫e^xcos(x)dx = (1/2) [e^x Ei[(i+1)x] + e^-x Ei[-(i+1)x]] + C

where Ei(x) is the exponential integral function.

Alternatively, the integral can be E×ρréššed in terms of the Fresnel integral as:

∫e^xcos(x)dx = (1/2√2) [√π/2 S(1/√2 + x/√2) + √π/2 S(1/√2 - x/√2)] + C

where S(x) is the Fresnel integral function.

Both of these solutions involve special functions that are not commonly used in elementary mathematics.
