Mathematica not plotting

  1. Feb 10, 2016 #1
    1. The problem statement, all variables and given/known data
    I've entered the following piecewise equation into Mathematica:

    Plot[Piecewise[{{sin (t), 0 <= t < \[Pi]}, {5 + 5 cos (t) + sin (t), \[Pi] <= t < 4*\[Pi]}, {10 cos (t) + sin (t), 4*\[Pi] <= t}}], {t, 0, 20*\[Pi]}]

    But I am getting a blank graph in return. I've proofread my input many times and can't find anything wrong with it. Can anyone help me get a graph generated?

    2. Relevant equations

    3. The attempt at a solution

    jedishrfu is correct. You should also use square brackets, not round brackets in functions. Sin[t] is the correct syntax. If you make those two modifications, it will work, as shown below. Screenshot from 2016-02-11 13:35:01.png

    Thanks to both of you! This ended up working just fine and I got the same graph that you did e.bar.goum
