To be more specific, we used the erf function in solving heat transfer partial differential equations in spherical coordinates in our heat & mass transfer class in our 3rd year of chemical engineering.

As an answer to the question posed it's hardly advanced.
The error function is pretty much just defined as the solution to the integral you were given (well with a few sign changes, that are easily worked around). You've just defined away your problem.
I have a problem with this one: Find the derivative of the function: {2^{3^{x^{2}}}}
It's answer is supposed to be something like this: {2^{3^{x^{2}}}}(ln 2)(\frac{d}{dx}({3^{x^{2}}})})
I think I have to use the chain rule, but if that's true why does this: {2^{3^{x^{2}}}}}{(ln 2)(\frac{d}{dx}({3^{x^{2}}})})
stay the same?
Shouldn't it be: {2^{3^{2x}}} or {6^{2^{x^{2}}}}
Could someone help me?
Please.

Sorry about that ^
This is what it's supposed to say.
It's answer is supposed to be something like this: {2^{3^{x^{2}}}(ln 2)(\frac{d}{dx}({3^{x^{2}}})})
I think I have to use the chain rule, but if that's true why does this: {2^{3^{x^{2}}}}(ln2)(\frac{d}{dx}(3^{x^{2}}))
stay the same?
