List how to find the reference angle in each of the four quadrants.

An angle in standard position always starts at this side
What is the initial side (positive x-axis)
3 patterns found on the unit circle.
Answers vary...
Trig functions that have a period of
pi
What is tangent and cotangent?
sin(pi/3)
What is
sqrt(3)/2
(5pi)/3 to degrees
What is 300 degrees?
All trig functions are negative except Tangent
What is Quadrant 3?
An angle in standard position ends at this side
What is the terminal side?
The terminal side of an angle passes through the unit circle at P(x,y). These trig functions can be used to find the coordinate.
The graphs of sec, csc, tan, and cot all have this type of line that guides the graph of the function but is not actually part of it.
What are Vertical Asymptotes?
cos((2pi)/3)
What is
-1/2
The arc length given
r=7 cm and theta=150 ^circ
What is
(35pi)/6
The terminal side of 1060 lies in this quadrant
What is Quadrant Q4?
The smallest positive angle coterminal with -100 degrees
What is 260 degrees?
The terminal side of an angle passes through the unit circle at (0, 1). The measure of the angle (in radians) is
What is
pi/2
?
The period of
y=4sin(pi theta)-8
What is 2?
csc((5pi)/6)
What is 2?
The 6 trig functions of angle A, whose terminal side contains the point (-8,15)
sin A = 15/17; cos A = -8/17; tan A = -15/8; csc A = 17/15; sec A = -17/8; cot A = -8/15
sin A > 0 and cos A > 0
What is Quadrant 1?
Two negative angles coterminal with 140 degreees
What are -220 degrees and -580 degrees?
The tangent of
pi/2 or(3pi)/2
What is undefined?
Given the parent function, list the transformations that occur on the new graph.
y=sin(theta) -> y=-2sin(4theta)+1
a = -2, so the amplitude shifts from 1 to 2 creating a vertical stretch by a factor of 2, as well as reflecting across the x-axis. b = 4, so the period changes from 2pi to pi/2, shrinking it horizontally. d=1, so it shifts the entire graph vertically up 1 unit.
tan((7pi)/4)
What is -1?
cot A=-4/3 and cos A<0
Find sec A and csc A.
sec A=-5/4 ; csc A=5/3
sin A < 0 and (tan A)(sin A) > 0
What is Quadrant 4?
The smallest positive angle coterminal with -800 degrees
What is 280 degrees?
Tangent is y/x. This is another way to represent tangent.
sin T / cos T
Graph
y=-3csc((theta)/3+pi/4)+2

sec(-(4pi)/3)
What is -2?
These angles (in radians) have a cosine of 1/2.
What is
pi/3 and (5pi)/3
