Can you take it from there?
I came across a rule that says the derivative of arctanx is . How would you differentiatie arctanx to get this?
Also, is there a way to show fractions with one factor on top of another, rather than side by side as in my example?
Ok, I see that we wind up with which contains which we can isolate if we set it equal to 1. I even see how we get the 1 since and , but how does ? I know the derivitave of but that doesn't explain why it's multiplied by in this example. Sorry, I haven't taken calculus since highschool and now I'm trying to relearn it.
