So we've been told we are the last of our kind. The last to be honoured to have been in a full class hosted by Mr. G. And it really is an honour. Mr. G, thank you for teaching us math and making school fun again. I think you made a positive difference in all of our lives. I know many of us were saddened that we would not have the opportunity to drop in on one of your classes at St. John's and scare your students with stories of what is to come, but hopefully one day we may still get that chance. Today an acoustic guitar video popped up in my YouTube recommended feed and I was reminded of chill guitar vibes and calculus. And while the math website is no longer listed on google, this forum still remains for those who were a part of something greater than themselves. We may no longer have G, but we have the good memories and the community he created with all of us. Thank you Mr. G

While redoing the tests from this year, I came across this question and its solution. It may just be that I'm forgetting something from a lesson we did back in March, but could you maybe please explain the process of what's going on here and why we're doing it? The part that really gets me is the line in the third column where you switch f(x) to e^ln f(x) and why that works? Thanks in advance

So here I am, taking a much needed break from studying, when I look to my teammate and observe G-man in my midst. Glad he didn't spontaneously ask me how many degrees are in 1.7 radians...

Mr. G, during the unit tests the activeboard was conveniently damaged from reoccurring blunt force so the inverse trig derivatives were stuck on it. Will those formulas be given to us on the exam? If not, for studying purposes, would we just need sin, cos, tan derivatives and inverse sin, cos, tan derivatives for the exam or are you dropping some inverse reciprocal trig derivatives on us?

Comrade G could you please assist me with a problem from the list. Textbook page 66, question 31. Question states: Evaluate the limit of (sinX) / (2X^2 - X) as X approaches 0. Please help me, Obi-G Kenobi, you're my only hope.

On the original unit 5 test you promised us we would have the option to either work with a ROC question or some other type of graphing question, so we could avoid one or the other if we so chose. Will that option also be available on tomorrow's rewrite?

Mr. G do you have the answer keys for our versions of the tests the first time we wrote them? If so can we please have a copy of those tests so we can see what we did wrong when we wrote them originally?

Hi Mr. G. Some of us have a quick question from the textbook review. #7. d) on page 510 reads: Express the following as a single log: 2 log 3 + 4 log 2. So at first glance this seems like we should be able to bring the coefficients up and get log 3 ^ 2 + log 2 ^ 4, which we can then use the Log Product law to turn into (skipping some steps): log144. However, the textbook says the answer is log128. Is this textbook error or are we doing something wrong? No video necessary by the way

What do you do if there is another fraction as part of the initial statement?

Hi Mr. G. So I'm still just a little confused here with "express () as trig function of angle x" questions. For example, sin(pi + x) = -sinx cos(pi/2 + x) = -sinx I understand using the equivalent expression rules to solve these. What I'm confused about is what dictates the sign (+ or -). For example in the cos(pi/2 + x) problem, the terminal arm is in quadrant 2, so sin is positive in that quadrant. Yet still the answer is -sinx. Is it the original cosine part of the problem that dictates the CAST?

I made a promise to this class. It's time to deliver. Take on Me (4K) and Never Gonna Give you Up (1080p60). Enjoy
