so far i can only do some types but when they vary its confusing!

lim x^2 − 5x + 2.

x->4

lim5 sin x

x->0 x

lim1

1 + sin x

x->0

1.

Only for Polynomials!

2.

The limit has the indeterminate form of 0/0, so we use L'Hôpital's rule and differentiate the numerator and denominator.

When you plug in 0 into the x, and you don't get an indeterminate form, you would get the limit (1).

Sin(x) equals 0 if x equals 0. - July 8th 2008, 04:07 AMEmmett
