V = 4/3πr^3
What should you use to convert radians to degrees?
x * (180/π)
Formula: Total Angle of a Polygon
TA = 180(n-2)
Special Right Triangle: 60-30-90
Special Right Triangle: 45-45-90
s, s, s(sqrt)s
Formula: Volume of a Pyramid
V = 1/3 lwh
Formaula: Volume of a Cone
V = 1/3 πr^2 * h
Formula: Volume of a Cylinder
V = πr^2 * h
Formula: Area of a Equilateral
How do you evaluate the difference of imaginary numbers/complex numbers?
(h+zi)(h-zi)
h^2 + z^2
What is the quadratic formula?
-b ± √(b^2-4ac) / (2a)
How do you find the discriminant?
Use b^2 - 4ac
b^2 - 4ac > 0, 2 real solutions
b^2 - 4ac = 0, 1 real solution
b^2 - 4ac < 0, 0 real solutions (NRS)
What is the equation used for exponential growth/decay?
y = a(1 ± r)^t
* a = initial, r = rate, t = time
What is the vertex form of a quadratic function?
y = a(x-j)^2 + h
* remember that (x-j) is a translation to the right
* remember that (x+j) is a translation to the left
What is the distance formula?
√( (x2 - x1)^2 + (y2 - y1)^2 )
How do you find the vertex of a parabola given an equation? (ax^2+bx+c)
(-b) / 2a
What is distance?
d = rt
distance = rate * time
How do you find the sum of solutions?
(-b) / a
What is the matching rule?
