1.	Sketch the graphs of the following curves on the same scale and the same axes:(i) y=cos x and y=cos x-π4(ii) y=cos 2x and y=cos 2x-π4(iii) y=cos x and y=cosx2(iv) y=cos2x and y=cos x
Answer» Sketch the graphs of the following curves on the same scale and the same axes: (i) $y = \cos x and y = \cos (x - \frac{π}{4})$ (ii) $y = \cos 2 x and y = \cos 2 (x - \frac{π}{4})$ (iii) $y = \cos x and y = \cos \frac{x}{2}$ (iv) $y = \cos^{2} x and y = \cos x$
