We often need to determine how many people are needed to complete a task within a given time.Alternatively, given a limited number of workers, we often need to determine how long it takes to finish a project.Well, since I couldn't create a calculator anywhere close to the one I discovered, I decided to accept their offer instead of trying to build one myself.
While researching the information needed to create an online algebra calculator for my site, I stumbled across an amazing math problem solver.
But even more amazing than the calculator itself, was when the creators offered to provide a miniature version of their calculator for free to my site's visitors.
Linear Algebra The site includes several java applets to investigate Graphs of Functions, Equations, and Algebra as well as HTML5 Applets for i Pads .
Topics explored are: equations of line, ellipse, circle, parabola, hyperbola, polynomials; graphs of quadratic, rational, hyperbolic, exponential and logarithmic functions; one-to-one and inverse functions and inverse trigonometric functions; systems of linear equations; determinants and Cramer's rule; inverse matrix and matrix multiplication; vectors, complex numbers, polar equations; absolute value function; slope of a line; angle in trigonometry, unit circle, solutions to trigonometric equations; graph shifting, stretching, compression and reflection.
Of course, cheating at math is a terrible way to learn, because the whole point isn't to know the answer to 2x 2 = 7x - 5, it's to understand the learn?
The app is actually designed to answer any kind of school question — science, history, etc. For other kinds of questions, Socratic kind of does a bit of Googling, and in my experience can typically find similar word problems on the wide internet, or from its own database of answers.Elementary statistics and probability tutorials are also included.All applets used to explore topics in mathematics in this site are grouped as online math software.It's an easy way to check your homework problems online.Click any of the examples below to see the algebra solver in action.Free trigonometry worksheets to download are in this site.Interactive Geometry Tutorials and Problems on topics such as reflection across a line, sine and cosine laws, central and inscribed angles, perpendicular bisector, medians and circumcircle of a triangle are also included.Also, I'd be remiss not to mention Photomath, which has been doing this since 2014, and actually has step-by-step explanations in the recently released Photomath paid version (there's a free trial).I like the Socratic interface and explanations a bit better, but I'm glad to see this is a vibrant market.It has trouble with word problems, but if you can write down a word problem in math notation it shouldn't be an issue.I also tried it on a weird fraction from an AP algebra exam, which it kind of failed at, but then I swiped over and it was showing me this graph, which included the correct answer: I love this app, not just because it would've helped 8th grade Paul out of a jam, but because it's such a computery use of computers.
