Is there a way to do what are known as the normalcdf( and invnorm( functions on an 84, on an 89 titanium? Typing in the longgggggggg function of a normal probability curve is tedious, and trying to do the equivalent of invnorm( requires my calculator to solve for a variable bound of an indefinite integral, and this takes 5 minutes minimum when my friends' 84 gets the same answer in milliseconds if that. Help?

Thanks

Anthony
