• You need to use square brackets for arguments of functions: Sin[2 Pi], not Sin(2 Pi) and Exp[] as well. Note also that the red parentheses indicate that they are mis-matched (e.g. not closed). Please post code as text, not as an image. Also checking whether p1, p2, p3, p4 show anything on their own is a good troubleshooting technique. – MarcoB Feb 19 at 15:32
