AllerCalc performs all of the functions necessary for high school Algebra and Geometry courses. AllerCalc is a good free alternative to buying an expensive scientific calculator.
Introduction: AllerCalc has more than one hundred functions, including algebraic, transcendental, trigonometric, hyperbolic, engineering, statistical, and financial functions. It performs numerical integration, differentiation, and root-finding. It comes preloaded with a list of common physical constants found in science and engineering. You can store results in an unlimited number of variables.
Box information and Reference
A cube is a three-dimensional figure with six matching square sides.
In a rectangular box, the length, width and height may be of different lengths.
l = length of box w = width of box h = height of box
You may assign values to variables which can then be used in subsequent calculations.
The variables will be saved when the program exits and may be re-used in subsequent sessions.
The following commands may be used with variables:
ShowVars: displays the variables' name and their values.
ClearVars: deletes the variables and their values.
A pyramid is a solid with a polygon base and connected by triangular faces to its vertex. A pyramid is a regular pyramid if its base is a regular polygon and the triangular faces are all congruent isosceles triangles.
l = length of base w = width of base h = height of pyramid
c and d = slant height of pyramid face (c= length face & d = width face)
AllerCalc has unlimited variable storage and more than 100 built-in math functions.
A trunctated pyramid volume is one third the height times (A + sqrt(A*B) + B)
where A and B are the area of the top and bottom faces.
A= area (A*B) and B= area (C*D)
In AllerCalc variables need not be only a character, "InterestRate" is a perfect name as well. And still, you can define as many variables as you want.
A cylinder is a solid with two congruent circles joined by a curved surface.
The expression: v = π*r²*h:
AllerCalc does not use implied multiplication. For multiplication you need to include the multiplication operator.
When an expression begins with an operator (+, -, *, /, %, or !), the previous calculation result is used as the first operand for the operator. Example:
A sphere is a solid with all its points equal distance from the center.
r = radius of sphere
In AllerCalc you just type the expression that you want to calculate and press Enter. You can see clearly what you typed along with the result in the scrollable display.
In geometry, a spherical cap is a portion of a sphere cut off by a plane.
The expression: A = 2*π*r*h:
R = radius of sphere
h = height of cap
a = radius of the cap (or plane)

Good news: Most polygons on the SAT have just four sides. You won’t have to tangle with any dodecahedrons on the SAT you take. There are five different types of quadrilaterals that pop up on the test. These five quadrilaterals are trapezoids, parallelograms, rectangles, rhombuses, and squares.
A circle is the collection of points equidistant from a given point, called the center. A circle is named after its center point. The distance from the center to any point on the circle is called the radius, (r), the most important measurement in a circle.
Triangles pop up all over the Math section. There are questions specifically about triangles, questions that ask about triangles inscribed in polygons and circles, and questions about triangles in coordinate geometry.
