Draghilev's method (solving systems of nonlinear equations)

**Example 1**.

x^2 - y * x + y^2 = 1

sin( 5 * x^2 ) + sin( 4 * y^2 ) = 0

Re: Draghilev's method (solving systems of nonlinear equations)

**Example 2**.

x^2 + y^2 - 8 = 0

sin( x * y ) * sin( exp( x * y ) ) = 0

Re: Draghilev's method (solving systems of nonlinear equations)

**Example 3**. Finding extremes: Himmelblau's function: f(x,y)=(x^2+y-11)^2+(x+y^2-7)^2

4 * x^3 + 4 * x * y - 42 * x + 2 * y^2 - 14 = 0

2 * x^2 + 4 * x * y + 4 * y^3 - 26 * y - 22 = 0

Re: Draghilev's method (solving systems of nonlinear equations)

**Example 4**.

tg( x * y + 0.1 ) - x^2 = 0

x^2 + 2 * y^2 - 1 = 0
