Promblem with integration

[Tim Wessman]

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.
