Consider the graphs of $y=\sin x$y=sinx and $y=5\sin\left(x+\left(\left(-60\right)\right)\right)$y=5sin(x+((−60))).
Consider the graphs of $y=\cos x$y=cosx and $y=2\cos\left(x+45^\circ\right)$y=2cos(x+45°).
The graph of $y=\sin x$y=sinx has been transformed into the graph of $y=\sin\left(x+\left(\left(-45\right)\right)\right)-2$y=sin(x+((−45)))−2.
