Mobile Math Pack
9.8 |
The Mobile Math Pack brings together four great apps:
1. Trigonomics - Tools for calculating triangles, exploring the unit circle and waves, looking up identities, and graphing with custom functions.
2. Geometrics - Constructs two-dimensional shapes when provided a minima set of dimensions and then calculates area and perimeter.
3. Algebraics - Utility for finding roots and graphically showing impact of varying coefficients of quadratic and cubic equations, prime factorization, and logarithms.
4. Base Station - Powerful base conversion tool that includes converting fractions and negative numbers, demonstrating IEEE floating point, and other useful utilities.
Details:
Trigonomics:
1. Triangle Solver - Provide the minimum combination of triangle side lengths and angles and Trigonomics draws the resulting triangle.
• Calculates the area and perimeter
• Alerts you when entered values cannot create a triangle
• Detects ambiguous case when entered values can create two different triangles
• Change a single value or multiple values at a time
• Rotate the triangle
2. Explorers
• Unit Circle - Understand the key relationships between an angle and its trig functions!
• Wave - See what happens to a wave when you adjust the amplitude, frequency, and phase.
• Right Triangle - Focus on a right triangle and all of its trig results.
3. Identities - Look up the most common (and some not-so-common) trig identities.
4. Graph - Plot up to three trigonometric functions at the same time.
• Enter your own custom functions!
• Draw once or loop the graph continuously
• Tap and hold on the graph to bring up a magnifying glass for precision
• See the unit circle being drawn as functions are plotted
Geometrics:
Shapes can be saved and combined with others to effectively calculate the area of any irregular shape. Geometrics can e-mail a report of the saved shapes and the total area! Geometrics supports these common two-dimensional shapes:
• Circular: circle, ellipse, segment, sector, ring sector
• Triangles: right, equilateral, isosceles, acute, obtuse
• Quadrilaterals: square, rectangle, trapezoid, parallelogram, rhombus
• Polygons: triangle to icosagon (20-sided)
Circle circumference and area is shown numerically or in terms of π. Special 30-60-90 and 45-45-90 triangles can be constructed with areas and perimeters calculated in terms of √3 or √2. Hexagon perimeter and area is shown numerically or in terms of √3.
Algebraics:
• Finds roots (real or imaginary) for quadratic and cubic equations.
• Graphically demonstrates impact of varying coefficients of quadratic and cubic functions.
• Performs prime factorization and determines greatest common divisor and least common multiple for up to 10 integers.
• Calculates logarithms for any base from 2 to 20, including e (natural log).
Base Station:
• Converts integers, fractions, and negative numbers for “common” bases (2, 8, 10, 16).
• Converts integers and fractions between any arbitrary base from 2 to 36.
• Demonstrates the relationship between bases 2, 10, and 16 through animated counting.
• For programmers (and the ultra-curious), there are tools for IEEE floating point, unicodes, and RGB colors.
• Offers a custom keyboard for binary through hexadecimal numbers for easy data entry.
