How would you compute the derivative of cos(t^3)? Would you use the chain rule? Does anyone have a good way of recognizing when to use chain rule and when not to?

I don't know, and I never will unless you tell me.

Derivative of log(x^2+y^3) ? I'm familiar with the derivative of log x but not when x is raised to a power or when y is involved. Could someone offer some help? And if you know of a website that fully explains this please let me know. Thanks.

Derivative of e^(-(1/3)x^2-(1/5)y^4) ? I need help figuring this out. I know that the derivative of e^5x is 5e^x but I'm not sure what to do when x is raised to a power or when there is another variable involved, such as y. Once again here is what I need to find: Derivative of...

If I'm given that someone releases a ball at x distance away from the ground how do you calculate how long it takes to fall? Another problem I have is finding the amount of time it takes to get to the top of an arc after you've thrown a ball and you're given the distance it is from the...

thank you sir. i think i understand it now. By the way, how did you make those cool symbols like for theta or the dot in between v1 and v2

I'm still confused. Here's an example. I am given a problem X "dot" X and that would give me x1*x1 + x2*x2 + x3*x3 . What is the point of having this information? What does the dot product mean geometrically?

Anyone familiar with dot products of two vectors? What does the dot product show, in other words what is the point of doing a dot product?
