Euler approximation
Appearance
Euler approximations use tangent lines at an initial point (xo,yo) to approximate the numerical value of a differential equation dy/dx=F (xo,yo) at (x, y). Euler's Formula uses the derivative of a function F(xo,yo) at a given point to approximate the value of f(x) a certain distance
Euler's Formula: y=yo+F(xo,yo)•h
