Question

This is not a question: List any hint/tip/trick/method for any of the following:: Finding integral(sub,trig,part, etc), improper integral, estimates sum error of series, parametric graphing, polar graphing, tangent equation at certain points for polar/parametric. Thanks all helps in advance: iHelp

Answer 1

Estimating sum: Have a good calculator with you. :-) Use both errors estimation tools (from the alternating series and from the integral test). Improper integrals: be sharp with limits, remember L'Hospital's rule and think about multiple discontinuities. Finding integral you get better with practice and time, there are tricks, but it's best if you can have a lot of practice.
