  1. Mathematics, Geometry and Trigonometry Review - Quadratic Formula: If ax2+ bx+ c = 0 then

  2. The angle αareequal between the transverse and • two parallel line: 180 - α α α α α

  3. For a line and its normal, the angle α are equal: V 1 1 2 α α α H V α 2 H

  4. Trigonometric Identities: • In the right triangle: Sin Ө = A/C or A = C sin Ө C cosӨ = B/C or B = C cosӨ A Ө tan Ө = A/B or tan Ө = sin Ө / cosӨ B C2 = A2 + B2

  5. In any triangle (general): (cosine rule ) C2 = A2 + B2 – 2AB cosβ A β B α Ө C (sine rule )
