I don't understand why the following gives a ConditionalExpression as a result. In[124]:= Integrate[Sqrt[u], {u, a^2 Sin[t]^2, a^2}, Assumptions -> { a > 0, Element[t, Reals]}] Out[124]= ConditionalExpression[-(2/3) a^3 (-1 +...
I ran it three times as you suggested, and indeed the first two take about the same time now. However, the third method (closed form with evaluation at the limits) remains about 50 times faster than providing the limits to Integrate (1.5 seconds when...
Oh, I figured it out... Constants->{x, y}. Sorry.
Hi I am a semiretired computer programmer. I used Mathematica v.2 and v.3 on Mac back when I was a structural engineering professor, and am now using v. 10, also on Mac. I have interest in many areas of math and physics and Mathematica eliminates...
