See how ordinary least squares regression fits a line to noisy data. Adjust the relationship and noise level to explore model fit and R².
Open tool →GraphInteractive binomial probability bar chart. Adjust n and p to see how the distribution shifts and spreads, with mean and standard deviation shown.
Open tool →GraphApproximate definite integrals with left, right, and midpoint rectangle rules. See how increasing the number of subdivisions improves accuracy.
Open tool →GraphSee how polynomial approximations converge to sin x, cos x, eˣ, or ln(1+x). Adjust the number of terms to watch the series home in on the function.
