Hi, Im a 31 year old computer programmer that want to revive some the calculus i learned at school, and learn new things as I go on. I seem to grasp things very fast as I remember while reading the tutorial here on the forum, but I need some help to check wether i have done those calculations right. I've read to lesson 6 for now and will continue if i get some answers of my questions here. Great tutorials by the way! I wonder what the final answers in those examples are. example lesson 5 (quotient rule): : 6 / (x2 + 16) example lesson 6 (chain rule): : 48x^8-33614 for number one exercise (in lesson 6) i get: = 6x2+23 for number two exercise i get: = 8x7+512x4+2048x3+131072 of course the first two examples are allready done by the tutorial except for the final answers. i just wonder if these answers are right or if i am on a blueberry trip link to the tutorials.
