TOPIC 2: Trig Limits TRIG LIMITS: If direct substitution doesn't work, most triglimits can be solved by expressing the limit as a product of these special trig limits. 1. so also Lim 1 0 sinx |-cosx cos X-1 Lim - 0, so Lim =0, BUT Lim so useless! 01-Cos 0 Limsin 0 SQUEEZE THEOREM is covered and used for some proofs in the teaching videos, but will not be tested Q.14 Please evaluate the following limits, without using...

1. Begin by making the substitution u=ex . The resulting
integral should be ripe for a trig substitution.
2. Make a choice of trig substitution based on the ±a2±b2u2 term
you see after the substitution. With the right choice, after
substituting and rewriting using sin/cos, you should again have
something fairly nice to solve as a trig integral.
3. The substitution sin(2θ)=2sin(θ)cos(θ) is useful after you
integrate.
4. Don’t forget to back substitute (through several
substitutions!) until everything is in...
