Most high school students come to math class equipped with the best calculator money can buy. Armed with their trusty calculator, no equation is too large or too complex to solve.Enlightened by their teachers who say they will use all these math equations into adulthood, they study hard and soak up the information like sponges.But unless you're a math professor, an engineer, or something equally as math-dependant, you won't need to use your scientific calculator to solve quadratic functions or parabola problems.The average Joe's real-life scenario mostly require … [Read more...]

## Convergence Calculator; How To Calculate Geometric Series?

Even in a second-semester calculus class, determining the sum of an infinite series is beyond the scope of what you'll typically be asked to do.One exception to this, however, is when you're working with an infinite geometric series, and you need to determine whether its sum is finite or infinite.For example, if you have 1/4 + 1/8 + 1/16 … the sum of this infinite series will ultimately approach – that is, converge upon – 1/2, and that makes its sum finite.Image source: DesmosOn the other hand, if you have 10 + 20 + 40 + 80 … the sum of the series only continues to … [Read more...]

## TI-82 Guide: Basics, Special Functions, And More

While the first handheld calculators performed basic mathematical functions – adding, subtracting, division – the first graphing calculator wasn't introduced until 1985.Additional features included executing tasks with variables, plotting graphs, and solving equations simultaneously.Plus, graphing calculators typically allow users to create programs for scientific or educational applications. Finally, because of the amount of information needing to be displayed, screens of graphing calculators are bigger than their more traditional counterparts.In 1993, Texas … [Read more...]

## Where to Buy an Integration Calculator

Integrals are a tough part of any mathematics curriculum. One of the defining pillars of Calculus, integration is key to understanding how infinitesimal data work in describing displacement, area, or volume. All of this isn’t easy work and to accomplish this without a calculator can be tough. It’s not impossible, of course, but any integration calculator can help you solve equations faster, and without the legwork that normally is needed. The basis of integrals is assigning numbers to functions that can provide deeper information on said data. What better tool … [Read more...]

## How to Use an Absolute Value Calculator

If you’ve ever taken an algebraic math class, which is most of the ones you’ll find in high school. You know about this vertical line-based sign. It’s an interesting expression. One that defines a value for a number called magnitude, without respecting its sign. This means that negative numbers are ignored, as an absolute value is only found within positive numbers. No negative numbers are allowed. Of course, with any calculations problems can become more or less challenging. Are often require more powerful technology to help you solve them. The most common aid … [Read more...]

## What the IRS Withholding Calculator Does for You

With the passage of the Tax Cuts and Jobs Act of 2017 signed into law in December, many wage earners are left to struggle with the question: how do I know what to withhold in 2018? Fortunately, the Internal Revenue Service (IRS) has anticipated that question, and has provided a handy tool to be used in calculating your tax implications for 2018. The IRS withholding calculator takes the guesswork out of determining how you can plan to meet your tax burden under the new legislation to avoid an unexpected tax bill, and to benefit from the reduced withholding … [Read more...]

## Graphing Inequalities with a Calculator

Solving and graphing linear inequalities with a calculator is nearly the same in theory as other linear equations, except the problem replaces the “=” comparison with a symbol representing inequality, such as < and >, Integers that are not equal contain a property referred to as inequality. A simple algebraic example of an equation representing inequalities is y<4x+5. Graphing typically involves the values of ordered pairs to identify the coordinates in order to plot x and y coordinates on a plane. The order of the coordinates is critical in representing … [Read more...]

## Basic Programming on the TI 83

Texas Instruments’ TI 83 Plus is powerful graphing calculator that puts scientific calculations, plotting, and graphic functions in the hands of students and technical professionals. First introduced by TI in 1996 as an evolution of the popular TI 82, the TI 83 programming calculator supports TI-Basic and Z80 assembly programming languages, providing options and flexibility for users. In 1999, TI succeeded the TI 83 with the even more powerful TI 83 Plus, while still enhancing the TI 83 with upgrades such as updated shape and elimination of the sloped screen that … [Read more...]

## How to Make a Fraction on a TI 84

Texas Instruments’ TI 84 graphing calculator is one of the company’s most popular calculators for programming and graphing applications. Continuing the evolution of the TI 83 series, TI 84 models provide many improvements over predecessors: Faster processing Three times the memory offered by TI 83 models Higher contrast display screen The TI 84 also retains full keystroke compatibility with the TI 83, which makes the upgrade easy for those who have enjoyed the power of earlier models. TI 84 calculators have all the features and support for performing a … [Read more...]

## What is Slope Intercept Form?

Equations of a line can take multiple forms, with variations in appearance, but each describing the same line in a linear equation. One such form is the slope intercept form: Most commonly stated, the formula is: y = mx + b m = slope of the line b = y-axis intercept of the line Slope intercept form is the most commonly used form of linear equations, where the coefficients utilized in the equation represent the slope and line intercept, hence the name of the form as the slope-intercept form. Making the Calculation There are many on-line … [Read more...]
