Area of a circular sector
A = 1/2O-R^2
A = area
O- = central angle of sector in radians
Effect vs affect
Affect: Verb, to produce change in something
Effect=usually a noun meaning result, an outcom
Moreover
as a further matter; besides.
Who/whom
Who is the subject of a sentence, can be replaced with "he" Whom is the object of a sentence, can be replaced with "him"
Horizontal
Slope = 0
Vertical
Slope = undefined
Sum of Supplementary in radians
Pie
Formula for the length of a circular arc
S = rO
S = arc length
R = radius
0 = central angle formed by the arc in radians
90° in radians
Pie / 2
parabola in vertex form
A(x)=−1/4(x−25)^2 + 625
describes a parabola in vertex form. The vertex of the parabola is the point (25,625) since there is a negative sign in front of the squared term, the parabola is facing downward. Therefore, the vertex describes a maximum.
Quadratic equation in vertex form
A(X- h)^2 + K
A positive: minium
A negative: maximum
( A > 0 opens up; A < 0 opens down)
Vertex: (H, K)
Axis of symmetry: X= H
("Symmetric with respect to the line X= -2)
Parabola in vertex form
P(s) = -(s - a)^2 + b
Negative sign in front of square term, facing downward. Describes maximum
