Angles
This is the complement of 53o.
What is 37o?
In a right triangle with one angle measuring 20o, this is the measure of the other acute angle.
What is 70o?
This is the term for angles whose terminal sides lie on an axis.
What are quadrantal angles?
This is the domain of all sin and cos functions.
What is all real numbers?
This is the amplitude of y=-2sin(3x)
What is 2?
This is the amount of degrees in one full rotation.
What is 360o?
This is the length of the hypotenuse of a right triangle with legs measuring 16cm and 30cm.
What is 34cm?
This is the quadrant that -150o lies in.
What is Q3?
This is the range of the parent(no transformations) sin and cos functions.
What is [-1,1]?
This is the formula for finding the period of a tan or cot function.
What is pi/B?
This is how many degrees equates to 3π/4 radians, as well as what quadrant the terminal side of the angle lies in.
What is 135o in Q2?
A right triangle has an acute angle labelled "A". The length of the side opposite A is 5 and the hypotenuse's length is 14. This is the exact value of cos(A).
What is (√171)/14?
DAILY DOUBLE! This is sin(60o).
What is (√3)/2?
This is where y=tan(x) will have asymptotes.
Wherever the cos(x) has an x-intercept.
or
x= π* k where k is an integer
This is the variable for determining phase shift of a trig function.
What is C?
This is the supplement of 2π/3.
What is π/3?
A 28-foot-long piece of wire is attached to the top of a pole at one end and nailed to the ground at the other end. The wire makes a 30o angle with the ground. This is the height of the pole.
What is 14 feet?
This is the sign of tan(-150o).
What is positive?
This is the range of f(x)=4sec(2x-3)-1.
What is (-inf,-5]U[3,inf)?
Graph y=2sin(3(x-2))-1
Amplitude = 2, Period = 2π/3, Phase Shift = 2, Midline : y = -1 I can't put images in this sorry :(
This is the angle in degrees from 0 to 360 that is coterminal with 39π/12.
What is 225o?
In a right triangle, c=12 and A=15o. These are the values of a, b, and B respectively (rounded to 4 decimal places).
What are 3.1058, 11.5911, and 75o?
This is cos(660o).
What is 1/2?
These are the values excluded from the domain of f(x)=-3tan(3x-3)-4.
What are x = π/6 + kπ/3 + 1?
Given y=sin(2x-pi)+1, this is the distance between two consecutive maximums or minimums.
What is pi?
