It does get the integral answer, but depending on the calculation it crashs due to the massive calculation needed

So the precise answer from the analytical solution, used twice to evaluate the integral from X=C to X=0.999999D, is 5570898.582

I searched online for help with this and some yahoo answers for the same problem said instead of hitting enter for the answer, to do f - d function, which is suppose to convert it to decimal, but it still doesn't work

The calculator will round off your numbers and give you the wrong answer to your problem

No wrong or improper answers!

This especially helpful for engineering and physics classes where the third decimal place on a seven digit number is the difference between a right and wrong answer

I would often input numbers and get incorrect answers.

This calculator is fantastic; having the ability to work with fractions, radicals, imaginary numbers, and numbers including π has been critical especially in electrical engineering courses, where decimal answers are inappropriate.

only gave it 4 stars because for what ever reason the built in temp converter going from F to C gave me a wrong answer

The number solver could use more memory though as it can not solve for some equations it also does not do calculus with degrees properly as it gives incorrect answer!!(I checked the mode)

Works as you'd expect of a more complex, but sub-graphing calculator
