I used selected problems to help Joshua review trigonometric ratios and functions. We wrote the six ratios equivalent to the six trigonometric functions given a specific right triangle and two of its sides. Then we did a real world problem employing trigonometry. I instructed Joshua to convert degrees to radians and radian angle measure to degrees. We also used trigonometry without calculators to
determine the trigonometric functions of several angles. Finally we used inverse trigonometric functions to determine missing angles. There was no assignment.
