The formulas particular to trigonometry have: sin (sine), cos (cosine), and tan (tangent), although only sin is represented here. In the formulas given here, you have: r (radius) d(diameter or distance) b (base or measure of a side) h (height) a, b, c (measures of sides) x, y (coordinates on a graph) m (slope) M (midpoint) h, k (horizontal and vertical distances from the center) θ (angle theta) and s (arc length). The main trick to using formulas is to know what the different letters represent.
