Solving equations, system of equations, integrals, primitive, limited,,,, For secondary school students, students and teachers. For example illustrates how to use: Solving equations, no equation: x ^ 2 +3 x +2 = 0 solve System of equations: x ^ 2 + y ^ 2 = 0, xy + x + y = 3 Solve Graphing: sin (x) plot Originally function: int xlnx Integral: xlnx, 1 .. e int Derivative: ln (x ^ 2 +1) der Derivative at 1 point: ln (x), x = 1 der Limit at the sites of: (x ^ 2-1) / (2x-1) lim Limit at 1 point: (2x
+1) / (x +2), x-> 1 lim Analysis multiplier: x ^ 4 +1 fac Archive calculations: (1 +2 i) ^ 2 / (1 + i) sim The maximum value, minimum (With or without conditions): x ^ 4-2x ^ 2 +3.1 <= x <= 3 max (min) x ^ 3 + y ^ 3, x ^ 2 + y ^ 2 = 2 min Total: 1 / (x (x +1)), x = 1 .. 100 sum...
