Some simple math



In [2]:

    
x=pi+2pi









    Out[2]:





3π



In [3]:

    
x/3









    Out[3]:





1.0π

Type promotion should work as expected



In [4]:

    
x-(4//3)*pi









    Out[4]:





5π/3



In [5]:

    
x+1









    Out[5]:





10.42477796076938



In [6]:

    
y=2pi
x/y









    Out[6]:





1.5

Exact results for sin and cosine of integer multiples of pi



In [7]:

    
(sin(2pi),cos(2pi))









    Out[7]:





(0.0,1.0)

We can define Ranges



In [8]:

    
range1=linspace(0,4pi,100)









    Out[8]:





0.0π:0.04040404040404041π:4.0π

And we get nice axes labels



In [9]:

    
y=sin(range1);
plot(x=range1,y=y)









    Out[9]:

Same for arrays



In [10]:

    
pirange2=[x*pi for x=0:0.02:1]
plot(x=pirange2,y=cos(pirange2.*3))
