Goals: Students know the trig ratio definitions. Students can explain and use the relationship between the sine and cosine of complementary angles. Students can use right triangle similarity to show side ratios are equal.
 * Understand in an acute angle the ratio value of sine and cosine are between 0 and 1, the tangent value can be anything greater than zero.
 * Students can use calculators to find value of trig functions in degree mode.
