输入：F(x)=integrate texp(-t) from 0 to x

网址： http://www.wolframalpha.com/input/?i=F%28x%29%3Dintegrate+texp%28-t%29+from+0+to+x

输入：d/dx( int texp(-t) from 0 to x )

http://www.wolframalpha.com/input/?i=d%2Fdx%28+int+texp%28-t%29+from+0+to+x+%29

输入： F(x)==integrate texp(-t) from ln(x) to x^2

http://www.wolframalpha.com/input/?i=F%28x%29%3D%3Dintegrate+texp%28-t%29+from+ln%28x%29+to+x%5E2

输入： d/dx (integrate texp(-t) from ln(x) to x^2 )
