Curated OER
Using Technology to Represent Mathematical Identities
Students explore the concept of trig identities. In this trig identity lesson, students use Mathematica to graph trig identities. Students see the trig identities graphically and enforce the notion that two trig functions can be equivalent.

Algebraic Atrocities
In this algebra activity, students prove whether or not the left side of an equation equals the right side. If it is false, students correct the equation. Equations include fractions, trigonometric identities, logarithms, square roots,...
