cos(30^o)

• - ½

• √3/2

• 2√3 /3

• ½

tan(300^o)

• -√3 /3

• ½

• 2√3 /3

• -√3

A full rotation of a circle can be measured in how many radians?

• 180

• 360

• π

• 2π

Radian measure can be found by:

• Finding the ratio of circumference and diameter

• Finding the ratio of radius and pi

• Finding the ratio of arc length and measure of central angle

• Changing calculator setting to radians

Increasing or decreasing the degree measure of an angle by an integer multiple of 360 or 2π results an a:

• Obtuse angle

• Coterminal angle

• Special Right Triangle

• Terminal Velocity

Positive angles in a Unit Circle start at the initial side and rotate

• Clockwise

• Counter Clockwise

• Anti-Counter Clockwise

• Super Clockwise

A circle with a radius of 1, with its center at the origin is know as the:

• Awesome Circle

• Unit Circle

• A Perfect Circle

• Rubrics Circel

During this Chapter I will have to:

• Memorize all the points on the unit circle

• Make an awesome 3D representation of the Unit Circle as a project

• Use Trig Functions

• All of the Above

What are the coordinates of 60° on the unit circle?

• (0, 1)

• (1/2, √3/2)

• (√3/2, 1/2)

• (√2/2, 1/2)
