(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

find the equation of the tangent to the curve defined by y=e^x that is perpendicular to the line defined by 3x+y=1

2. Relevant equations

m= 1/3 (negative reciprocal of y=-3x+1)

derivative of e^x=e^x

3. The attempt at a solution

i keep getting stuck at 1/3=e^x ( i know theres a way to solve for x i just cant remember)

the answer is x-3y+(1+ln3)=0
