i think you r very poor to operate calc or in maths!!! ;)
English please?
Clearly you didn't learn anything, because you never notices the answers were way off.
If it was radians instead of degrees, which is the most likely case (a lot of scientific calculators default to radians whereas most early math classes work in degrees) then the answers are RADically different, to the point where someone who was paying any attention really should have noticed ie sin(30)=-0.988 in radians and .5 in degrees.
how wud u not notice that...calculators are just suposed to help you not do all the work for you :P
If you can't tell the difference between degrees and radians you deserve to fail.
Ah well, at least you won't ever make that mistake again. However, it usually becomes fairly obvious if it's the wrong way around, and even if you don't notice after one set of odd answers to a question, didn't you twig on the second or third question?

You had it set to "radian" when you wanted "degree" am I right?
Hahaha. And you didn't notice this at all...Shame on you, not the calculator.
