short and sweet!

Hello everyone! I’m super busy this week tutoring my students for their finals (which mostly take place next week). Yesterday I had 13 hours of students, yikes!! I’m going to try to blog everyday this week but am going to keep my posts pretty short in the essence of my time crunch

Here’s a video on how and why it’s good for my BC Calculus students to know the cylindrical shell method for finding volumes of revolution (in addition to their preferred methods of disks and washers)…

And here’s a video explaining how to look at a graph of a derivative and answer questions about the original function. I ALWAYS get a ton of questions on how to do this! My AB Calculus students have been doing this very recently…

is it xmas yet?

One more week and then Winter Break! All of my students have their finals in January so this week is filled with lots of chapter tests and quizzes. I know it’s a busy time for all of you…and not just in math!

My AB Calculus students have been studying the relationship between position, velocity and acceleration. They have been working on word problems involving all three which can definitely be confusing. Hopefully this example will help you sort through similar problems. I’m planning on doing another video on this same subject next time too. It’s just too much to cover in only one video!

My BC Calculus students recently learned integration by parts. This is a method that helps you take a very difficult integral and rewrite it as a much easier one instead. I’ve shown two very frequent types of integration by parts…the tabular method where you keep taking the derivative of “u” until you get 0 and a wrap-around problem where you eventually get the same integral that you started with (which doesn’t seem like something that would be very helpful, but it is!)

Have a great week! Just keep looking forward to winter break, and I know you can make it!!

rough monday

Oh wow, it was hard hearing that alarm go off this morning after a relaxing Thanksgiving break! I so much just wanted to rollover and go back to sleep! I did make it here today though, and if we all push through it’s only a quick, busy 3 weeks until Winter break

I’m anticipating that my BC Calculus students will be working on solving differential equations by separation of variables this coming week. I’ve included two examples in my video. If the timing works out properly, I’m planning to do a few word problems using separation of variables next week.

And right before Thanksgiving my AB Calculus students were working on related rates which is where they will be picking back up again today. I’ve worked through one of the very commonly seen “ladder” problems.

See you tomorrow for Precalculus!

a busy week…then Thanksgiving!

Only one more full week of school before Thanksgiving! Which also means you probably have lots of tests and quizzes coming up. Teachers like to squeeze everything in right before you have time off don’t they?!

My AB Calculus students are actually having their huge test over derivatives TODAY! I’ve wrapped up the derivative chapter by explaining inverse trig, logarithm, and exponential derivatives here…

My BC Calculus students have recently been taking integrals which require u-substitution. I’ve shown a shorter method (fewer steps) than the traditional u-substitution method. It’s always nice to have some shortcuts in Calc

Good luck navigating your way through what I’m sure will be a busy week!

Welcome back, Calculus Monday

Hello to Monday morning and waking up to some Calculus! Sundays are my longest day and latest night of tutoring so Monday mornings are always a challenge. I’m a tea drinker (I’ve never gotten into the taste of coffee) so that always helps me through my most difficult mornings!

My AB Calculus students are still working their way through what is probably the longest chapter in their book (it’s Chapter 3 for them). It goes from the long way of doing derivatives (limit definition) through the power rule, product rule, quotient rule, chain rule, implicit differentiation, inverse trig function derivatives, exponential and logarithm derivatives and then their TEST! Whew…that’s a lot for one chapter. They very recently learned implicit differentiation so that is our video for today…

My BC Calculus students are wrapping up their beginning integrals chapter. It has taught them how to evaluate integrals in different stages…before learning the “easy” way! I’ve given a run-down of the ways you can take an integral leading up to (and including) the “easy” way in this video…

I hope you all have a great week! Hang in there…hopefully my videos will make your lives a little easier
