Find dy/dx in terms of t if x=te^t, y=-10t-10e^t.
I know the steps but I don't know what e^t is....Is the derivative just e^t? Please help!

Can you show me the process you use?

anonymous · Answer

so I would just get the derivative of both of them and then put dy/dx. So i would get dx=e^t and idk how to get dy. Im not sure if dx is even correct...

anonymous · Answer

the answer just has to be in dy/dx form but I'm having trouble getting the derivative of e^t.....

hawkfalcon · Answer

Interesting. I believe that you would need to put it in terms of dx/dt fist.

hawkfalcon · Answer

d/dx(e^t)would be dt/dx(e^t) >.< Not sure how you would make it in terms of dy/dx. sorry:(
