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.

   Volume = l*w*h
   Surface Area = 2*(l*w+l*h+w*h)

 Pyramid Information and Reference
   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.

   Volume = l*w*h/3
   Surface Area = l*c+w*d+l*w

 Topless Pyramid Information and Reference

  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.
Ref. see AllerCalc Topless Pyramid

fig. 5  Topless Pyramid Volume and Surface Area
   Volume = (h/3)((a*b)+(c*d)+√((a*b)(c*d)))
   Surface Area = x+y+u    u=(a*b)+(c*d)
   x= 2*(a+c)*h/2    y= 2*(b+d)*h/2

 Cylinder Information and Reference
  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:
  2+2 =
+3 = (treated as ANS + 3, or 4 + 3)

    r = radius of cylinder
    h = height of cylinder

Ref. see AllerCalc Cylinder

fig. 7  Cylinder Volume & Surface Area
   Volume = π*r²*h
   Surface Area = 2*π*r(r+h)

   A circular cone has a circular base, which is connected by a curved surface to its vertex.
The vertex is the top or pointed area of the cone.

    r = radius of cone base

 A= Total Surface Area
   A= pi*(R1+R2)*sqrt((R1-R2)^2+h^2)+pi*(R1^2+R2^2)
 V= Volume
   V= (pi*h/3)*(R1^2+R2^2+(R1*R2))

 Topless Cone = Cone Frustum
 Topless Cone = Truncated Cone

SAT Test - Math
SparkNotes SAT Polygons
   Good news: Most polygons on the SAT have just four sides. You wont 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.
SparkNotes SAT Circles
   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.
SparkNotes SAT Triangles
   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.
