Solve math high chool

math online, edu, math , high school , solve

Solve problems such as solving equations school, equations, simultaneous equations, find antiderivative, integral, derivative calculation, find the maximum value, minimum value of a function suitable .... with the students and math teachers.

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
