※ 引述《STARS74721 (....)》之铭言：
: 1. find the equation of tangent line of f(x) when x = 2 where f(1)=e
: and df(x)/dx = 3x^2f(x)
df(x) = df(X)
______ 3x^2dx => S _______=S3x^2dx=> ln|f(x)|= x^3+c
f(x) f(x)
ln|f(x)| x^3+c
e = e
x^3 c c
f(x)= e * e => f(1)= e*e c=0
x^3
f'(x)= e *3x^2
e^8*12(x-2)=(y-e^8)
长的不太像答案的东西 ...
