Lesson summary
Lesson summary
- Always start with direct substitution. If the denominator is not zero, the limit is the result.
- If the result is 0/0, factorise the numerator and denominator and cancel the common factor.
- If a square root appears, multiply by the conjugate and then simplify.
- Use the limit laws for sums, products, quotients and powers.
