Skills available for West Virginia Precalculus standards
IXL's Precalculus skills will be aligned to the West Virginia Next Generation Content Standards and Objectives (Common Core) soon! Until then, you can view a complete list of Precalculus standards below.
Standards are in black and IXL math skills are in dark green. Hold your mouse over the name of a skill to view a sample question. Click on the name of a skill to practice that skill.
11-12. Represent complex numbers and their operations on the complex plane.
11-12.M.SRM.CN.4 Represent complex numbers on the complex plane in rectangular and polar form (including real and imaginary numbers), and explain why the rectangular and polar forms of a given complex number represent the same number.
11-12.M.SRM.PRR Polynomials, rational, and radical relationships
11-12. Use polynomial identities to solve problems
11-12.M.SRM.PRR.1 Know and apply the Binomial Theorem for the expansion of (x + y) to the n power in powers of x and y for a positive integer n, where x and y are any numbers, with coefficients determined for example by Pascal's Triangle.
11-12.M.SRM.PRR.2 Understand that rational expressions form a system analogous to the rational numbers, closed under addition, subtraction, multiplication, and division by a nonzero rational expression; add, subtract, multiply, and divide rational expressions.
11-12. Extend the domain of trigonometric functions using the unit circle
11-12.M.SRM.M.11 Use special triangles to determine geometrically the values of sine, cosine, tangent for pi/3, pi/4 and pi/6, and use the unit circle to express the values of sine, cosine, and tangent for pi–x, pi+x, and 2pi–x in terms of their values for x, where x is any real number.
