All 2 lessons in Trigonometric Functions

  1. 1. Ratios in a Right Triangle and the Exact Values of 30°, 45° and 60°

    Find one trigonometric ratio from another in a right-angled triangle, derive the exact sine, cosine and tangent of 30°, 45° and 60° from a half-square and a half-equilateral triangle, use complementary angles, and evaluate expressions exactly by rationalising surd denominators.

  2. 2. Trigonometric Ratios of Any Angle

    Define sine, cosine and tangent for any angle from 0° to 360° using the coordinates of a point on its terminal arm, derive the quadrant sign table, find the other ratios given one ratio and the quadrant, evaluate the five axis angles, and find a quadrant or an angle from two sign clues.
