x^2 - 5x + 6 = 0An equation is solved automatically x + y = 10, x - y = 4A system of equations, separated by commas y = x^2 - 4Graph a function; trace shows zeros, max/min, intersections r = 4cos(2θ)Polar graph, θ from 0 to 2π (3cos(t), 2sin(t))Parametric curve, t from 0 to 2π. Numbers alone make a point x^2 + y^2 = 16Any curve in x and y y < x/2 - 5Inequality, shaded. Dashed edge means not included a := 3Store a value; later lines use it f(x) := x*sin(x)Define a function; it is also graphed $3The result of line 3 sqrt(x), ln(x), abs(x)Roots, natural log, absolute value limit(sin(x)/x, x, 0)Limit as x approaches 0 defint(x^2, 0, 1, x)Definite integral from 0 to 1 sum(k^2, k, 1, 10)Sum for k from 1 to 10 determinant(matrix([1,2],[3,4]))Matrices: also invert, transpose
