Section 9.2 The Law of Sines
Up until now we have dealt only with right triangles.
But obviously there are triangles (called oblique
triangles) that do not contain a right angle. An oblique
triangle can have all three angles acute (less than 90)
or one ob

UNIT CIRCLE TRIGONOMETRY
The Unit Circle is the circle centered at the origin with radius 1 unit (hence, the unit
circle). The equation of this circle is x 2 + y 2 = 1 . A diagram of the unit circle is shown
