What's my quadrant?
This is the quadrant where sin(theta) < 0 and cos(theta) < 0.
What is Quadrant III?
Suppose (12, 16) is a point on the terminal side of an angle in standard position. This is the value of tan of the angle.
What is 4/3?
This is the reference angle for 330 degrees.
What is 30 degrees?
This is the single trig function that csc(x)tan(x) reduces down to.
What is sec(x)?
This is the amplitude for y = 5sin(x).
What is 5?
This is the quadrant where sec(theta) > 0 and tan(theta) < 0.
What is Quadrant IV?
Suppose (3, -4) is a point on the terminal side of an angle in standard position. This is the value of sin of the angle.
What is -4/5?
This is the reference angle for 5pi/4 radians.
What is pi/4 radians?
This is the single trig function that tan(x)cos(x) reduces down to.
What is sin(x)?
This is the period for y = cos(4x).
What is pi/2?
This is the quadrant where csc(x) > 0 and cot(x) > 0.
What is Quadrant I?
Suppose (-7, 2) is a point on the terminal side of an angle in standard position. This is the value of sec of the angle.
What is -7/sqrt(53) (or -7sqrt(53)/53)?
This is the reference angle for 635 degrees.
What is 85 degrees?
What is (cos x)^2?
This is the phase shift for y = cos(x + pi/5) + 2.
What is -pi/5?
This is the quadrant for the angle 9pi/13 radians.
What is Quadrant II?
Suppose sec(theta) = 6/5 and tan(theta) < 0. This is the value of tan(theta).
What is -sqrt(11)/5?
This is the third quadrant angle where sin(theta) = -0.988.

What is 261 degrees?
What is 60 degrees?
What is y = 7cos(0.5x)?
This is the quadrant for -458 degrees.
What is Quadrant III?
Suppose sin(theta) = 3/8 and cos(theta) < 0. This is the value of cos(theta).
What is -sqrt(55)/8?
This is the 4th quadrant angle theta where cos(theta)=1/2.
What is 300 degrees?
We know cos(75 degrees) = 0.259. That means cos(105 degrees) = this value.
Name the equation for the graph of a sine function with a reflection in the x-axis, horizontal shift right pi/2 and vertical shift up of 2.
