What formula will help you convert an angle from degrees to radians?
theta * (pi)/(180^o)
100
The side of a right triangle that lies across from the right angle, the longest side of a right triangle.
hypotenuse
100
Reference angle of 75o
75o
100
The binomial factors of
x^2-10x+24
(x-6)(x-4)
200
The point where the graph crosses the x-axis. Also called roots or zeroes.
x-intercept

When completing the square, how can you use the coefficient of the x term to find the constant of the squared binomial?
divide by 2 or divide by 2a
200
The side of a right triangle that is across from the focus angle when finding trigonometric ratios.
opposite side
200
A coterminal angle of one that is 45o.
405o or -315o
200
The trigonometric ratio of the sine of angle.
sintheta=(opposite)/(hypoten use)
300
The turning point of a parabola.
vertex
300
The Pythagorean Theorem
a^2+b^2=c^2
300
The side of a right triangle that is between the focus angle and the right angle when finding trigonometric ratios. This side is "next to" the angle but is NOT the hypotenuse.
adjacent side
300
A coterminal angle of one that is -133o.
227o or -493o
300
If a quadratic has a discriminant equal to 0, then it has "this many" real, rational roots.
1
400
Highest or lowest y value for a parabola, can be found by using the y coordinate of the vertex.
minimum or maximum
400
The formula for the x coordinate of the vertex of a parabola
x=(-b)/(2a)
400
An angle is in "this position" if it's vertex lies on the origin and the initial ray lies on the positive x-axis.
standard position

Degree measure for an angle that measures
(4pi)/3

When
g(x)=f(x+3)-1
g(x) represents a shift of f(x) in this way.
three units to the left and one unit down
500
The line that splits a parabola into 2 identical pieces.
axis of symmetry
500
The quadratic formula
x=(-b +- sqrt(b^2-4ac))/(2a)
