418 Functions and commands
similarity With two points (B and A), a real (k) and an angle (a1) as
arguments, returns a point that is the point similar to A across
center B with angle a1 and with scaling coefficient k. With an
axis (Dr3), a real (k) an angle (a1) and a point (A) as
arguments, returns a point that is the point similar to A across
the axis given by the line with angle a1 and with scaling
coefficient k.
similarity(Pnt(B) or
Dr3,Real(k),Angle(a1),Pnt(A))
Example:
similarity(0,3,angle(0,1,i),point(2,0))
dilates
the point at (2,0) by a scale factor of 3 (a point at (6,0)),
then rotates the result 90° counterclockwise to create a
point at (0,6)
simult Returns the solution to a system of linear equations or several
systems of linear equations presented in matrix form. In other
words, in the case of one system of linear equations, takes a
matrix A and a column matrix B, and returns column matrix X
such A*X=B.
simult(Mtrx(A),Mtrx(B))
Example:
simult([[3,1],[3,2]],[[-2],[2]])
gives
[[-
2],[4]]
SIN Sine: sinx.
SIN(value)
sincos Returns an expression with the complex exponentials rewritten
in terms of sin and cos.
sincos(Expr)
Example:
sincos(exp(i*x))
gives
cos(x)+(i)*sin(x)
single_inter With two curves or two surfaces as arguments, returns one of
the intersections of the two curves or surfaces. With to curves
or surfaces and a point or list of points as arguments, returns
an intersection of the curves or surfaces that is nearest to the
point or not in the list of points.
single_inter(Curve,Curve,[Pnt(A)||LstPnt(L)])
