Strategy in finfing mimits
- F(a) = b/0 where b is not a zero. Vertical
asymptote (Probably) example: lim x-1 1/x-1
- F(a)=b where b is a real number We are
done! (Probably) example. Lim x-3
x^2=(3)^2=9
- F(a)= 0/0 Inderetminate form
Example: lim x-1 x²-x-2/x²-2x-3
- Factoring example
Lim x- -1 x²-x-2/x²-2x-3 can be reduced to
Lim x- -1 x-2/x-3
- Conjugates example Lim x-4 √x-2/x-4
can be rewritten as Lim x-4 1/√x+2
- Trig identities example
Lim x-0 sin(x)/sin(2x) can be rewritten as
Limx-0 1/2cos(x)
