Chapter 10 & 18 – Trigonometry and Circular Measure

When students have completed this lesson they should be able to:

• Know the shapes of the graphs of sine, cosine, and tangent for all angles
• Know, or be able to find, exact values of the sine, cosine and tangent of certain special angles
• Solve simple trigonometric equations
• Use identities involving sin, cos, and tan
• Know how to convert from degrees to radians and vice versa
• Use formula for the length of a circular arc, and for the area of a circular sector
• Know the graphs and symmetry properties of sin, cos, and tan, when angle is in radians
• Know the meaning of arcsin, arccos, and arctan, their domains and ranges
• Solve trigonometric equations with roots expressed in radians
