Question

determine the equation of the tangent to the curve defined by y=xe^-x at the point A(1,e^-1)

Answer 1

yea, thats what i got, but the answer is y=1/e

Answer 2

now i believe i gotta substitute the coordinates to calculate b value

Answer 3

with the given points

Answer 4

slope at point A is 0. so your equation is:
y-1/e =0

Answer 5

same thing...

Answer 6

yea

Answer 7

go ahead

Answer 8

okay

Answer 9

, prove that y"=y/25
