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!

    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...

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

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

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