Some Taylor and Maclaurin series on this fine Monday! "You guys think I know calculus? I just make this stuff up every day!"

One last tie before spring break - and some sage advice about error bounds: "Engineers: try not to make the bridge collapse and kill lots of people!" Have a great spring break Chestys!

First tie back from Spring break! And what did Mr. Ellis do over Spring break, you may be wondering? "A whole lotta nothing!"

Today we learned many tests to run on infinite series, listed next to Mr. Ellis' head for your convenience... you still have to do the homework though! Student: "Wait, this is just thinking about it!" Mr. Ellis: "It is! And actually all of math sort of is..."

Happy Friday! Very fun tie today! We're still working our way through the LAST Calc unit - crazy to think we've come this far! "I guess you could write x=-1 as [-1, -1], but definitely not as (-1, -1). That's just an empty interval... and your points would be empty too!"

Winnie the Pooh tie today as we approach (like a limit?) our last test before the AP exam! "Here's the silver lining: I don't care! So I'm not gonna simplify... if [the AP gods] don't care, I don't care."

Rare Monday Tabasco tie today! It also has baseball on it because Mr. Ellis is helping throw the first pitch at an LHS baseball game tonight! "Here's another non-separable diff. eq. We know its non-separable because if you try to separate... it's not separable."

Mr. Ellis wore animal ties all week to celebrate Earth Day, so of course he ended with a lion on this fantastic Friday! "You and I can agree all day long, but the AP gods on their magical hill..."

Our final practice AP test with Mr. Ellis was handed back today! Now we set our sights on our final challenge: the real AP exam! Student: "Why'd you make this question?" Mr. Ellis: "I didn't make this question!... I just email the AP people 'WRITE THIS PROBLEM LIKE THIS!'"

Fun fact! Last night, Mr. Ellis (for fun) spent 4 hours working on a spreadsheet exploring the problem seen to his left and now he has a 900k row spreadsheet on his Mac! "My wife texted me at like 1AM and asked where I was so I had to tell her I was downstairs working on this!"

Last day with Mr. Ellis before the AP exam, so of course he had to rock the Tabasco tie! "I brought everyone mints for 'MINT-al' energy on Monday!" Get in all your last-minute studying this weekend, because Monday is go-time!

AP Calc exam is tomorrow! If you're reading this, this is your reminder that one of the best preparations is to get plenty of sleep! No quote today, but if I had to guess, Mr. Ellis would probably say: "Good luck tomorrow! You guys are gonna do great! Just think about it!"

AP exam is done! Hooray! As per tradition, we watched Stand and Deliver, and got to sign our ceiling tile posters... Mr. Ellis may not be teaching at LHS next year but we can still do it! Very special tie from Mr. Ellis' favorite AB students!" "...Citation needed!"

Last (?) day in calc for most people! We played pictionary and charades as a class with some... mixed success! "OH, IT'S A CHIMPANZEE! (drawing was supposed to be Superman...)" Campbell's soup tie! "This one is an OG tie!"
