Sum of infinite terms of geometric sequence, S = a / (1 - r) Sum of n terms of geometric sequence, S n = a (r n - 1) / (r - 1)

The n th term of the geometric sequence is, a n = a Sum of arithmetic sequence = n/2 (OR) n/2 Nth term of arithmetic sequence, a n=a 1+(n−1)d Here are the list of formulas that are very useful in solving Algebra 2 problems. These 12 chapters in Algebra 2 are given as:Ĭhapter 1: Linear Equations and InequalitiesĬhapter 4: Cartesian and Coordinate SystemĬhapter 9: Factoring and Solving by FactorizationĬhapter 10: Exponents And Exponential FunctionsĬhapter 11: Radical Expressions and EquationsĬhapter 13: Data Analysis And Probability Algebra 2 is divided into approximately 13 chapters and each chapter is divided into several lessons. Forever.Algebra is divided into numerous topics to help for a detailed study. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.įor free.

Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We tackle math, science, computer programming, history, art history, economics, and more. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.Ībout Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. In these tutorials, we'll cover a lot of ground. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. Without it, it's impossible to move forward. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. It's also seen as a 'gatekeeper' subject. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process.
