Quadrantal Angles end on the quadrants - they are angles that are multiples of 90 degrees. If one of the sides of the angle passes through a point on the axis, we cannot draw a triangle to calculate the six basic trig functions. Thus, we have to remember in this case that:
y = the opposite side
x = the adjacent side
the distance between the origin and the point: the hypotenuse
We also calculated missing angles within a triangle. This can be done by using the 2nd - inverse functions on the calculator above the three trig functions. We can fill in all missing sides and angles of a triangle.
The second review sheet was given out today, and you know how to do everything on it! Due date is September 12th, early due date is September 11th for 10 bonus points. Friday is the last day to retake the last quiz.
