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.
x*e^x=e^x
x=1
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
