Select a subject to explore its lessons. Each lesson explains the concept and its real-world applications.
Full scientific calculator with history.
Solves ax² + bx + c = 0 using the quadratic formula. Shows discriminant analysis and all steps.
Compute trig functions and their inverses in degrees or radians.
Evaluates f'(x) at a point using the central difference method: f'(x) ≈ [f(x+h) − f(x−h)] / 2h. Use standard JS math notation (e.g. Math.sin(x), x**2, Math.exp(x)).
Numerically integrates f(x) from a to b using Simpson's 1/3 rule with n=1000 subintervals.
Solves dy/dx = f(x,y) numerically from x₀ to xₙ given initial condition y(x₀) = y₀.
Paste comma-separated numbers to compute descriptive statistics.
