CXC CSEC General Proficiency math topic:

TRIGONOMETRY

These are the specific learning objectives that CXC has set for this CSEC math topic

 CONTENT: All the topics listed for geometry as well as: Sine and cosine formulae - simple practical applications; trigonometrical formulae for the area of a triangle; latitude and longtitude; distances on the earth's surface treated as that on a sphere. SPECIFIC OBJECTIVES: The student should be able to: 1. Determine the trigonometrical functions of angle θ° for -360° ≤θ ≤ 360°; 2. recognize and use the trigonometrical ratios of special angles, for example, 30° 45° and 60° in the fractional or surd form; 3. Use the sine and cosine formulae in the solution of problems involving triangles (the ambiguous cases will be excluded); 4. Calculate the area of a triangle given two sides and the included angle by means of the formula: Area of ΔABC = ½ab sin C; *5. draw the graphs of the circular fuunctions sine, cosine adn tangent of θ° for -360° ≤θ ≤ 360°; *6. Solve practical problems involving heights and distances in three-dimensional situations; *7. Calculate the distance between two points on the earth, treated as a sphere, measured along parallels of latitude or meridians; *8. Determine the latitude and longtitude of a point on the earth's surface given it's distance from another point on the same parallell of latitude or on the same meridian. * Optional objectives
