What I mean is I need a place to practice like you can do on khanacademy. He asks you to find d/dx of 3x^2+5x+10 for example and you would write: 6x+5 and the system will confirm your answer.
I need a place where I can also practice integral calculus and more diverse power rule/chain rule. Thanks.
I suggest to find a good book of calculus for practice and a good C.A.S that will help you ....to verify your answers
the best C.A.S is mapple but Mathematica and Mathlab ond others do an excellent job as well .
