Signals and systems/Sinusoidal signals

$$x(t)=A*cos(b*t+c)$$ where $$A$$ - amplitude $$b=\frac{2\pi}{T}$$; $$T$$ - period $$c$$- phase

cosine - is an even function $$x(t) = x(-t)$$ sine - is an odd function $$x(t) = -x(-t)$$

sine function possible to flip horizontally and then flip vertically, as result -same function and plot
