check my answers plz
1. y = xe^x - 1 at x = 0
My solution:
f^1(x) = e^x+ xe^x
f^1(0) = e^0+ 0e^0
=1
Therefore,
y-(-1) = 1(x-0)
y = x - 1
2. y = x Inx at x = 1
My solution:
f^1(x) = x(1/x) + Inx
= In x
f^1(1) = In 1
= 0
Therefore,
y-0 = 0(x-1)
y= 0
Addition question... how can I use math symbols in the forum... I mean the real symbols not like ^ sqrt these kind thing
