Students know the definitions of the secant and cosecant functions, and can graph them. Students know that the tangent of the angle a line makes with the x-axis is equal to the slope of the line. Students know the definitions of the inverse trigonometric functions, and can graph the functions. Students compute, by hand, the values of the trigonometric functions and the inverse trigonometric functions at various standard points. Noon Project Revisited 11.
Students use trigonometry to determine unknown sides or angles in right triangles.
Noon Project Revisited 13. Students know the Laws of Sines and the Law of Cosines, and apply them to problems. Noon Project Revisited 14. Students determine the area of a triangle given one angle and the two adjacent sides. Noon Project Revisited 15.
