RE: Promblem with integration
Since there is no exact closed form answer here (not without using some stuff not supported in any calculator), it returns the input unevaluated. Two ways to get a numeric approximation.

1. Press SHIFT-ENTER (to run approx( ) on your last input)
2. Put a "." in one of your limits. int(sin(x^2),0.,8) <-- note the 0. and not just 0

Both of those will immediately evaluate a decimal result.

The reason it works in HOME as stated already is that the X variable is an approximate valued number. Hence, it is just like putting the "0." in the second option as it triggers the approximate numerical calculation.
