Geometry
We just finished testing lengths of sides of a triangle
to determine if the triangle is acute, right, or obtuse.
We are now starting to work with special right
triangles: 30-60-90 and 45-45-90.
Algebra II
We are continuing our work with matrices. Soon we
will learn how to solve a system of linear equations in
two different ways: 1) Reduce an augmented matrix
to reduced row echelon form, 2) Solve a matrix
equation using inverses.
Algebra I
We are learning to solve a system of linear equations
in two different ways: 1) Substitution, 2) Elimination.
Precalculus
We have finished our chapter on exponential
modeling. We are now starting a deeper look into
trigonometry.
