This is weird:

"Find the equation of the line tangent to equation e^x and passes through the origin."

How would you do that algebraically without a calculator?

do you have to do y=(e^x)*x and then try to find the intercept?

oh never find, stupid me, I figured it out.



so slope is e

so equation is y=ex.

the equation for the slope of y = e^x at ANY point (derivative) is y = e^x
