HI, I'm new to maple and am having trouble taking partial derivitives. I couldn't find anything in the documentation that seemed to resolve the situation, and can't be the first person to stumble through this part of Maple.

Namely, it seems like the exponential function causes an extra "ln()" term to show up in the solution. I've tried with e^(y) and exp^(y) but nothing seems to be working. When i use the same markup up in wolfram and matlab and Ti-CAS i get the "correct" solution.

I attached a screen showing my input and output.

thanks for any insight!
