This tool combines a traditional scientific calculator with advanced graphing capabilities. It lets you plot multiple functions, evaluate expressions using either radians or degrees, and even solve equations using Newton's method. The calculator records your past calculations so you can revisit them at any time. Everything runs right in your browserβno additional downloads or plugins required.
The memory buttons (MC, MR, M+, M-) let you store and recall numbers just like a handheld calculator. The angle mode toggle switches between degrees and radians for trigonometric functions. You can simplify algebraic expressions, take derivatives with respect to x, compute definite integrals, and graph multiple functions simultaneously. A zoomable chart with crosshair coordinates helps inspect curves, while the solver finds approximate roots for your custom equations. You can even share interactive graphs with a link or QR code.
Enter expressions using standard math notation. For example, type sin(pi/4) or sqrt(2). Click Plot to visualize functions over a range of x-values, adjusting the min and max fields to zoom in or out. Hover over the graph to see coordinates. When solving equations, provide a reasonable starting guess for faster convergence. Use the Share button to copy a link or QR code of the current graph.
Students can explore algebra and calculus concepts by plotting derivatives, computing integrals, or checking homework. Engineers and scientists will appreciate the quick equation solver and ability to graph multiple curves for comparison. Because all calculations happen locally, it's also a handy privacy-friendly option. Sharing graphs via URL or QR code makes collaboration effortless.
Use parentheses liberally to ensure expressions evaluate as expected. When graphing, try splitting multiple functions with commas, like sin(x), cos(x), to compare them on the same axes. Hover to read coordinates and use the integration tool for area calculations. For large or small numbers, standard scientific notation works well.
