Integrating periodicity

Display the integral of a few periodic functions with zero offset, e.g.

• cos(t)
  
• 3*sin(t)
  
• A triangular wave
  
• A square wave

Is the integral periodic?

Now add an offset value to the functions, e.g. plot:

• cos(t)+1
  
• 3*sin(t)-2
  
• A triangular wave with offset 1
  
• A square wave with offset 2

Is the integral still periodic?
