WebPlot of the cosine and sine functions By comparing the sinusoidal waveforms of Figure 3.3, we see that the cosine function will be the same as the sine function if the latter is shifted to the left by 7⁄2 radians, or 90°. Thus, we say that the cosine function leads (is ahead of) the sine function by n/2 radians or 90° .
