Maths study guides

A deep-dive NY Regents Algebra I guide to the expressions-and-equations strand. Covers reading and rewriting expressions, polynomial arithmetic and factoring, linear and literal equations, inequalities and the sign-flip rule, systems by substitution and elimination, and the three methods for solving quadratics, with the credit-based exam technique the Regents rewards.

A deep-dive NY Regents Algebra I guide to the functions-and-statistics strand. Covers function notation and key features, linear versus exponential models, graphing quadratics, one-variable statistics (center, spread, outliers, box plots), and two-variable regression (line of best fit, slope and intercept, residuals, correlation), with the credit-based exam technique the Regents rewards.

A deep-dive NY Regents Algebra II guide to the exponential, logarithmic, and trigonometric strand. Covers the inverse log-exponential relationship and log properties, solving exponential and logarithmic equations and modeling growth, radian measure and the unit circle, graphing sinusoids, and arithmetic and geometric sequences and series, plus the credit-based exam technique the Regents rewards.

A deep-dive NY Regents Algebra II guide to the polynomials-and-rationals strand. Covers polynomial division and the Remainder and Factor Theorems, zeros, multiplicity and end behavior, rational expressions and equations with extraneous solutions, radicals and rational exponents, and complex numbers with the discriminant, plus the credit-based exam technique the Regents rewards.

A deep-dive NY Regents Algebra II guide to the statistics-and-probability strand. Covers the normal distribution and z-scores, conditional probability and the addition and multiplication rules, sampling and study design with simulation and margin of error, and regression with residual plots, plus the credit-based exam technique the Regents rewards.

A deep-dive NY Regents Geometry guide to the congruence-and-proof strand. Covers rigid motions and the transformational definition of congruence, the triangle congruence criteria and CPCTC, compass-and-straightedge constructions, angle and triangle theorems, and parallelogram and quadrilateral proofs, with the credit-based proof technique the Regents rewards.

A deep-dive NY Regents Geometry guide to the similarity, trigonometry, and circles strand. Covers dilations and AA similarity, right triangle trigonometry, circle angle and segment relationships, coordinate geometry and partitioning, and volume with cross sections and density, plus the credit-based exam technique the Regents rewards.
