[BUG]Solving the limit problem - yangyongkang - 03-11-2019 03:04 PM
I will make a long story short, this is a question in the calculus exercises.I solved it with XCAS but got a wrong answer.The problem code is as follows
Code:
limit(int(sqrt(tan(t)),t=0..sin(x))/int(sqrt(sin(t)),t=0..tan(x)),x,0,1)Both XCAS and Maple get the same answer 0
Wolfram alpha does not seem to solve it.
However, this answer is wrong, the correct answer should be 1
We can see the answer from the graph
Code:
plot((int(sqrt(tan(t)), t = 0 .. sin(x)))/(int(sqrt(sin(t)), t = 0 .. tan(x))), x = 0 .. 1)Sorry my poor English
Finally, I hope that XCAS can solve the partial differential equation and wish XCAS getting better and better.

Indeed, fixed (in Xcas for Firefox).
