Q. If dy/dx = e^x / x and y(1) = 2; find an approximate value for y(3). Use a technique from calculus or technology to help you solve the problem. It is impossible to find an antiderivative.(adsbygoogle = window.adsbygoogle || []).push({});

My thoughts / ideas:

I thought this was a separable equation, and could separate the x and y variables and then may be just integrate both sides.

But I don't think this is possible, Since the question clearly says "It is impossible to find an antiderivative".

Any ideas.
