# how do I enter 2sin|1−3√2|cos|1+ 2√3|

when I enter it in SageMath as `2 * sin * abs(1-3 * sqrt(2))*cos*abs(1+2 * sqrt(3))`

it does not run the code? your help would be very appreciated :)

Sample question: How do I compute symbolic integrals like $\int{sin(x) tan(x)} dx$

How do I understand the result of symbolic integrals

why is symbolic comparison so slow?

The problem you've written makes no sense. Please clarify: What is the argument for sin? Should sin * be sin( ? If so where should the closing parenthesis be? Same could asked for cos. Assuming you mean 2 * sin(abs(1-3 * sqrt(2)))*cos(abs(1+2 * sqrt(3))) then I have Sage running without a problem, with an answer of about 0.049579.

oh I see, it seems I did not enter the correct amount of parentheses for the problem. thank you for the help :)
