[BUG]Solving the limit problem
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.

study hard, improve every day

Indeed, fixed (in Xcas for Firefox).

Yay! Perhaps the Prime CAS can be updated a few times a year?
