******************************************************************************************
Reference angle is the angle measurement from the x-axis. <em>There is no such thing as a negative reference angle.</em>
-183° is 3° from the x-axis so the reference angle is
*******************************************************************************************
Coterminal means the same angle location after one or more<em> </em>rotations either clockwise or counter-clockwise.
To find these angles, add <em>or subtract</em> 360° from the given angle to find one rotation, add <em>or subtract</em> 2(360°) from the given angle to find two rotations, etc.
To find ALL of the coterminals, add <em>or subtract</em> 360° as many times as the number of rotations. Rotations can only be integers. In other words, you can only have ± 1, 2, 3, ... rotations. You cannot have a fraction of a rotation.
Given: 203°
Coterminal angles: 203° ± k360°, k ∈ <em>I</em>

Answer:
a) h = 0.1: , h = 0.01:
, h = 0.001:
, b) The instantaneous velocity of the ball when
is
feet per second.
Step-by-step explanation:
a) We know that describes the position of the ball, measured in feet, in time, measured in seconds, and the average velocity (
), measured in feet per second, can be done by means of the following definition:
Where:
- Position of the ball evaluated at
, measured in feet.
- Position of the ball evaluated at
, measured in feet.
- Change interval, measured in seconds.
Now, we obtained different average velocities by means of different change intervals:
b) The instantaneous velocity when can be obtained by using the following limit:
And we finally evaluate the instantaneous velocity at :
The instantaneous velocity of the ball when is
feet per second.
