Maybe, I work in modern business and never needed it though. None of my colleagues did either (i asked).
a branch of mathematics that was widely thought to be usless untill not long ago was the study of prime numbers, and now this knowledge is used to encrypt e-mails and the like.
maths has applications accross a whole range of topics. one of my flat mates, studing geography, was asking me for help with maths stuff yesterday, as was a biologist. it's also useful if you get lost at sea...
although this is all (apart from the primes/number theory bit) applied maths. applied maths is boring. the real joy in maths is found in pure maths. the grin without the cat 🙂
i still have not found a reason for studying group theory. something about symmetry...?

Originally posted by rhbwell, one of my lecturers gave a lecture on how if you cut up an orange into infinitly many pieces and then put those pieces back together you shall get a single orange of the same size as one of the others. or somethingh along those lines anyway-i didn't actually make it too that lecture (it was a random one and nothing to do with my course).

but if you had a degree in maths, heck, if you had a degree in anything* would you be stacking oranges for the rest of your life?
*apart from an arts degree. we all know they are useless 😉
Originally posted by CoconutCorrect. But did you carry the four?
Your answer is wrong. Work backwards to check it. To take the derivitive of (1/3)*sin(x^3)+C, remember that you must take the derivitive of x^3 and put it out front of the sin function (cos after you have differentiated). So that is of course 3x^2. Multiplied by the (1/3) before the sin gives us the original derivitive.
