Question

for my physics class we are expected to know how to do derivatives, i have a TI-89 calculator and supposedly they can do derivatives. but im not sure how. i enter it the equation on correctly but i dont get the right answer, any idea why this is?

Answer 1

Press "2nd+8", expression (no equals sign), ",", variable by which you wish to take the derivative of, ")"

Let's say we want to take the derivative of \(x^2\)
The input line should look like this\[d (x^2,x)\]
