Graphs
Tools where the answer is best seen on a graph: from a simple function to fitting a curve to measurements.
4 tools
- Function plotterSeveral functions at once, with zeros, extrema and intersections.
- Derivatives and integralsSymbolic derivatives, the tangent at a point, and definite integrals with the area under the curve shaded.
- Regression and curve fittingLinear, quadratic, cubic, exponential, logarithmic and power regression from (x, y) points, with R² and a chart.
- Parametric, polar curves and inequalitiesGraphs of x(t), y(t) and r(θ) curves, and inequalities f(x) > g(x) solved with the solution set shaded.
How to type functions
All the tools use the same notation: x^2, 2x, sin(x), √x, e^x. You can leave out the multiplication sign.
