Question
1. What is the value of θ (round to the nearest hundredth; two decimal places)? Remember to put it in degrees
For the circle x +y =r:
Circumference = 2ar
P(x.y)
If 0 is an angle in standard position, whose terminal
ray passes through P(x, y) on the circle, then:
sin e = Y
cos e =
tan 0 – L
sin 0+ cos 0 =1
180 degrees = I radians
