Apr 13, 2018 · To get from (1) to (2), you just replace x with −x. You get the − in front because sin(−x)=−sin(x), but the identity is still the same.
Jun 15, 2016 · Explanation: Suppose that, f(x)=ecosx. Now we know that the Principal Period of cosine fun. is 2π. That is to say, cos(x+2π)=cosx. Hence, f(x)=e ...
