__Function file:__ **involute(m,n,r,t,q,fmt)**

This function plots an involute, defined by:

- 1 involute - starting point in [m,n], radius r, angle t; all values are scalars
- n-involutes - starting points in [m,n], radius r, angle t; all values are vectors (expect fmt)

Parameters

*m,n* describe centre of the involute in axes x,y.

Parameter

*r* describe radius of the involute.

Parameter

*t* is angle of generating, it set in radians.

Parameter

*q* is for change compute points on the involute, so quality.

Parameter

*fmt* describe format of involute lines. You can change format of lines (color and style) and format of points.

Example:

*
involute(3,-4,5,2*pi,100,"m");*

__Function file:__ **cycloid(m,n,r,t,q,fmt) **

This function plots a cycloid, defined by:

- 1 cycloid - starting point in [m,n], radius r, angle t; all values are scalars
- n-cycloids - starting points in [m,n], radius r, angle t; all values are vectors (expect fmt)

Parameters

*m,n* describe centre of the cycloid in axes x,y.

Parameter

*r* describe radius of the cycloid.

Parameter

*t* is angle of turn of generating circle, it set in radians.

Parameter

*q* is for change compute points on the cycloid, so quality.

Parameter

*fmt* describe format of cycloid lines. You can change format of lines (color and style) and format of points.

Example:

*
cycloid([2,0,3],[-1,0,2],[2,3,2.5],[4*pi,4*pi,4*pi],[80,120,100]);*

__Function file:__ **epicycloid(m,n,r1,r2,t,q,fmt)**

This function plots an epicycloid, defined by:

- 1 epicykloida - starting point in [m,n], radius r, angle t; all values are scalars
- n-epicykloid - starting points in [m,n], radius r, angle t; all values are vectors (expect fmt)

Parameters

*m,n* describe centre of teh epicycloid in axes x,y.

Parameter

*r1* describe radius of generating circle.

Parameter

*r2* describe radius of fixed circle.

Parameter

*t* is angle of turn of generating circle, it set in radians.

Parameter

*q* is for change compute points on the epicycloid, so quality.

Parameter

*fmt* describe format of epicycloid lines. You can change format of lines (color and style) and format of points.

Example:

*
epicycloid([2,0],[5,0],[5,6],[2,3],[2*pi,3*pi],[100,120]);*
