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.

Represent complex numbers and their operations on the complex plane
M.SRM.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.
M.SRM.5 Represent addition, subtraction, multiplication and conjugation of complex numbers geometrically on the complex plane; use properties of this representation for computation. (e.g., (-1 + √3 i)³ = 8 because (-1 + √3 i) has modulus 2 and argument 120°.)
PRR Polynomials, Rational, and Radical Relationships
Use polynomial identities to solve problems.
M.SRM.10 Know and apply the Binomial Theorem for the expansion of (x + y)n 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.
M.SRM.11 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.
M.SRM.21 Compose functions. (e.g., If T(y) is the temperature in the atmosphere as a function of height, and h(t) is the height of a weather balloon as a function of time, then T(h(t)) is the temperature at the location of the weather balloon as a function of time.)
Extend the domain of trigonometric functions using the unit circle.
M.SRM.27 Use special triangles to determine geometrically the values of sine, cosine, tangent for π/3, π/4 and π/6, and use the unit circle to express the values of sine, cosine, and tangent for π–x, π+x, and 2π–x in terms of their values for x, where x is any real number.
