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

Sine is a ratio of:

• opposite and adjacent sides
• opposite side and hypothenuse
• adjacent side and hypothenuse
• a² + b² = c²

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

A periodic function get their name because they:

• Have behavior that repeats infinitely
• They are punctuation functions
• Are finite in nature
• They attract bears

Domain of sine and cosine function is:

• (-1, 1)
• [-∞,∞]
• (-∞, ∞)
• { x | x ≠ 0}

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
