Algebraic Fractions: Domain, Reduction, Operations
Find the domain, cancel factors, convert to a common denominator, and discard extraneous roots.
Change the base and doubling time, mirror the exponential into a logarithm, add logarithms on a slide rule, and solve exponential equations.
This simulation uses a physically accurate engine to calculate real-time interactions based on established scientific principles. It allows you to visualize phenomena that are typically invisible or happen too fast or too slow to observe in a traditional classroom setting.
This interactive STEM simulation lets you study the process visually by adjusting parameters and observing results in real time. Launch the model and experiment with settings to see how different variables affect the outcome.
The simulation content is available immediately once launched: the interactive model loads in your browser and requires no additional software.
This knowledge applies across science, engineering, and everyday life — from understanding natural phenomena to using modern technology.
This simulation is designed for middle and high school students, teachers, and anyone interested in STEM education.
Yes, this interactive simulation is available for free educational use.
Absolutely! Our simulations are fully optimized for both desktop and mobile browsers.
Find the domain, cancel factors, convert to a common denominator, and discard extraneous roots.
Build squares and rectangles to see why (a+b)², (a-b)², and a²-b² work.
Learn to measure the world in degrees! Estimate angles by eye, use a virtual protractor, and construct specific angles with high precision.
Design the fastest descent and compare it with a straight line, Galileo's arc, and Bernoulli's cycloid.
An amazing way to calculate π! Throw virtual needles onto a lined floor and see how the probability of crossing the lines is related to the famous number.
Roll the circle to find π, drag the inscribed angle’s vertex, and check tangents and the cyclic quadrilateral.
Count outcomes on a decision tree, tell arrangements from combinations, and build Pascal’s triangle.
Play with space! Draw geometric shapes in the Cartesian coordinate system, translate them along axes, rotate, and reflect them across the center or lines.
