What is Cotangent?
One-half of a rotation around the Unit Circle is...
What is 𝞹 or 180 degrees?
Arc length measures...
What is the length of the exterior curve formed by an angle on the circle?
Area of a sector measures...
What is the area (space inside) of a piece of the circle?
When θ is measured in radians, the formula for area of a sector is...
a. A = 1/2r2θ
b. A = 𝞹r2
c. A = 2𝞹r
What is a?
A = 1/2r2θ
To convert from degrees to radian measure, you should multiply by...
a. 𝞹
b. 𝞹/180
c. 2𝞹r
What is b?
multiply by 𝞹/180
Amplitude on a function's graph measures...
What is the height of the curve (from the x-axis to either the maximum or minimum) ?
Frequency of a function's graph measures...
What is the number of times the function repeats itself?
True or False?
"The inverse of sine is cosecant"
What is FALSE?
The inverse of sine is sin-1
The reciprocal of sine is cosecant... it's the flipped version (NOT the inverse).
Tan-1 (-1) = ?
What is 7𝞹/4 or -𝞹/4 ?
Remember: tan = y/x & tan-1 is restricted to the right side of the circle (Quadrant I & Quadrant IV)
Sin-1 (1/2) = ?
What is 𝞹/6 ?
Remember, sin is the y value of a function, & sin-1 is restricted to the right half of the Unit Circle (Quadrant I & Quadrant IV).
Cos-1 (1/2) = ?
What is 𝞹/3 or 60 degrees ?
Remember: cos is the x-value of a function, & cos-1 is restricted to the top half of the Unit Circle (Quadrant I & Quadrant II).
tan (𝞹) = ?
What is 0?
Remember: tan is sin/cos, which is y/x using the numbers in the brackets (the coordinates or ordered pair).
The inverse of cosine is restricted to which quadrants or part of the Unit Circle?
What is Quadrant I & Quadrant II?
Remember: the inverse of cosine function only uses the top half of the Unit Circle!

The inverse of tangent is restricted to which quadrants or part of the Unit Circle?
What is Quadrant I & Quadrant IV?
Remember: the inverse of tan function only uses the right half of the Unit Circle!
The inverse of sine is restricted to which quadrants or part of the Unit Circle?
What is Quadrant I & Quadrant IV?
Remember: the inverse of sine function only uses the right half of the Unit Circle!
