Algebra 2 Definition and 59 Threads

I would like to take the derivative of the following function with respect to Gt: $$\mathrm{G}_{t+1}=\mathrm{g}_{0}\mathrm{e}^{-qHt}$$ I think that the answer is either -1 or ##\mathrm{e}^{-qHt}-1## If you could show the calculations that would be a great help. Thanks very much.

In order to write next step in all four equations above l used the definition of radicals. ##\sqrt a=b## means ##b^2=a##. Squaring both sides also works. I don’t know if it’s right. I mean I read that ##(\sqrt a)^2=a##. But I don’t know if we can apply this on expressions. Main problem is if we...

I am currently learning some maths from “Precalculus by James Stewart”. I was wondering if that’s ok? Is it ok to just dive straight into it or go back and brush up my algebra 2 ? I was wondering what are some good textbooks on algebra 2 by the way? Thank you. (This is all for the love of physics).

I'm trying to review some high school maths and work my way to Calculus and Linear Algebra, and I found these three translations of Japanese maths textbooks translated by the AMS and edited by Kunihiko Kodaira. The AMS links to them are: https://bookstore.ams.org/cdn-1669378252560/mawrld-8/...

I am currently in year 9 (9 grade for those in US) and I have a really rusty and a weak math background. I have 2 months of summer holidays coming up. I should be done with pre algebra in mid December. During my summer holidays I have more than 50 hours a week avalible for study and I was just...

My situation is that I'm 17, and graduated high school early due to the CHSPE test. The only math I have any real knowledge of is algebra 1, since I forgot geometry and barely got into algebra 2 before I graduated. No books have worked, Gelfand's Algebra frustrated me exceptionally because it...

Hey PF, as my thread a week or two ago said I am currently planning on taking a college Calc and Analytic Geometry class with formal education only up to Geometry. I am very proficient in Geometry, good in algebra 1, have some experience in Trig and a little in Algebra 2. For this reason I was...

Hey, I am a freshman in High School and I have a very superior IQ but I am in normal classes. This is due to ADHD and I used to be lazy in school. Anyways, algebra 1 is VERY boring. I want to teach myself geometry, algebra 2, Pre Cal, and Calculus because I love math. Also I feel like it will...

So I made another post to explain my position, and I need to learn Algebra 2B this summer (The B part or second half) In order to test out of it next school year and then take trig. So I was wondering if anyone knew a good source to self teach algebra 2B, maybe an online course, or a website...

So, I want to teach calculus to my math club. I know that differentiation and integration is easy. But how do I teach the CONCEPT of DERIVATIVES and INTEGRATION to people who only learned algebra 2? Algebra 2 people because that's the bare minimum of mathematics you need to learn calculus...

Are there any well-written algebra 2 trig book that gives understandable contents for beginners?

Hi, I am wondering if it would be better to do Pre-Calculus online with the 2nd semester Algebra 2. Or take college algebra online with 2nd semester Algebra 2. If I go the Pre-Calculus online with 2nd semester Algebra 2, my senior year I will be taking Calculus AB 1st semester and Calculus BC...

I am trying to learn algebra 2 by myself but I am having some troubles. I bought a textbook and was trying to learn the material just by reading the book and doing the exercises but I couldn't figure out how to do the exercises very well. So next I tried to use Khan Academy to help me understand...

I want to learn algebra 2 and trigonometry and was going to try to learn algebra 2 first then learn trigonometry after that. However after thinking I thought it would be more engaging to learn both at the same time. So my question is, should I learn algebra 2 first, then trigonometry, or...

I am a freshman in high school I would like to major on physics and most likely in mathematics in college so I figured it would be worthwhile to start learning more math. In school I am currently learning geometry and next year my class will cover Algebra II. I was wondering what would be the...

Hi everybody, I wanted to know what the difference is between algebra 1 and 2. The reason I'm asking is because I'm teaching myself mathematics and at moment I'm studying algebra 2 using study books. However, it seems that a lot of the material is a repeat of algebra 1. Greetings, Shawn

Sry, this will be the last question^^ Its a similar to the problem i ve postet before. Maybe if i can solve the first problem i can solve this to. But what i don't understand is that notation. I ve circled it with a red line. Does anyone know what this means? Thx Mumba
