If a=2i+4j-5k the direction of cosines of the vector a are
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° . WebWe're defining perpendicular to mean the theta between-- two vectors a and b are perpendicular if the angle between them is 90 degrees. And we can define that. We can take two vectors, dot them. Take their dot product. Figure out their two lengths and then you could figure out the angle between them.
