Hello can anyone please explain W.E 37? I understand odd and even graphs but I dont understand this example.
Its notation is so different to W.E 35.

If n is even, then (1)^n = 1. If n is odd, then (1)^n = 1.

Compare WE35c to WE37a. What they are doing in WE37a is using the (1)^n notation to avoid having to write out the solutions in two parts, like they have done in WE35c.
