Basic Trig Angle Calculator	Given an angle θ, this calculates the following measurements: Sin(θ) = Sine Cos(θ) = Cosine Tan(θ) = Tangent Arcsin(x) = θ = Arcsine Arccos(x) = θ = Arccosine Arctan(x) =θ = Arctangent	YES	YES	YES
Pythagorean Theorem	Figures out based on user entry the missing side or missing hypotenuse of a right triangle. In addition, the calculator shows the proof of the Pythagorean Theorem and then determines by numerical evaluation if the 2 sides and hypotenuse you entered are a right triangle using the Pythagorean Theorem	N/A	YES	YES
Pythagorean Theorem Trig Proofs	Shows the proof of 3 pythagorean theorem related identities using the angle θ: Sin²(θ) + Cos²(θ) = 1 Tan²(θ) + 1 = Sec²(θ) Sin(θ)/Cos(θ) = Tan(θ)	N/A	N/A	N/A
Sum to Product and Product to Sum Formulas	Given two angles in degrees of u and v, this determines the following: * Sin(u) ± Sin(v) * Cos(u) ± Cos(v) * Sin(u)Sin(v) * Cos(u)Cos(v) * Sin(u)Cos(v) * Cos(u)Sin(v)	N/A	N/A	YES
Sum-Difference Formulas	Given two angles u and v in degrees, this calculates the following: * Sin(u + v) * Sin(u - v) * Cos(u + v) * Cos(u - v) * Tan(u + v) * Tan(u - v)	N/A	N/A	YES
Triangle Solver	Solves a triangle including area using the following solving methods Side-Angle-Side (SAS) Angle-Side-Angle (ASA) Side-Side-Angle (SSA) Side-Side-Side (SSS) Area (A) is solved using Herons Formula	N/A	N/A	N/A
