Perfect for algebra, trigonometry, and geometry, this set of calculators feature logarithms, scientific notation, pi, angle units, factorial functions as well as sine, cosine, tangents, and their inverse.
The scientific caculator is the same make and model as the projector calculator, allowing your students to follow along at their desks and complete the same functions you complete on the overhead. With the projector model, semi-transparent, colorful keys and LCD are enlarged on your overhead projector, allowing you to demonstrate advanced trigonometric and logarithmic functions for the whole class to see. Both are solar-powered, so no batteries are required. Size: projector model: 7 1/4"L x 4"W x 1/4"H; calculator: 3" x 5".
