B adj Max / Mini values for sin and cos are 1 and -1 Any triangle A Special Triangles c C a Isosceles Equilateral Scalene b Right - Angle No angle the same 90o All lengths & Angles equal (60o) 2 sides & 2 angles equal Ratio values for sin and cos are between 0 and 1 Converse is also true ! SG For Any triangle Triangle & Trig. Angles in a triangle add up to 180o Sine Rule Cosine Rule a = stretches / squashes graph in y direction b = how times it repeats in 360o c = moves graph up / down
