Basic and Advanced Math Concepts
Area of a Traingle:
What are the dimensions in a 30, 60, 90 triangle?
What are the dimensions of a 45, 45, 90 traingle?
What is the area and circumference of a circle?
What is the volume of a 3D cube?
What is the volume and area of a cylinder?
Picking Numbers IN:
Eliminate the obvious:
on complex questions.
Figures in the SAT are:
always drawn to scale, unless labelled.
Parenthesis, Exponents, Multiply, Divide, Add and Substract.
3,4,5 and 6,8,10.
Triangle Inequality Theorem:
When you add lenght of any two side of any traingle, result must be greater than the length of third side.
Sum of terms/Number of terms.
If you are solving for a percent:
If you need to solve for a part:
When square root in a term in a equation:
square both sides to eliminate the square root.
Choose a number.
Because absolute value is distance:
its always positive.
set of values for which the function is defined.
set of outputs or results of the function.
equation whose graph is a straight line.
Slopes of perpendicular lines:
Slopes of parellel lines:
Alteration of any function.
shifts grap of f(x) n units up.
shifts grap of f(x) n units down.
shifts grap of f(x) n units left.
shifts grap of f(x) n units right.
Equation of a straight line:
When a line is tangent to a circle:
it is perpendicular to the radius that it intersects.
tilt upward to the right.
tilt downward to the right.
have a slope of zero.
have an undefined slope.
have equal slopes.
have negative reciprocal slopes.
Union of sets:
(U) symbol. set of elements that are in either or both of the different sets you start with.
Intersection of Sets:
(n) symbol. set of elements common to the sets you start with.
y=kx, where k is nonzero constant.
xy=k, where x and y are variables and k is constant.
desired outcomes/possible outcomes.
