# Algebra II

**Algebra II** picks up where Algebra I leaves off. Quadratic relations are expanded to include Conic sections in Algebra II while exponential and logarithmic functions are introduced and explored. Linear equations are reviewed then expanded to three variable graphs. Quadratic graphs will now deal with the complex numbers and completing the square is taught as a third method of determining the parabola's zeros. Algebra I uses primarily the quadratic formula and factoring. Matrices and determinants are explored in depth. Matrix operations of addition, subtraction and multiplication are practiced while using Cramer's rule for determinants. Sequences and series are introduced as arithmetic or geometric. Recursive rules for sequences and infinite geometric series begin the student's journey into abstract mathematics. Trigonometric graphs, identities and equations are added to basic trigonometric ratios begun during geometry.
