a sin (bx + c). Place x — V x, y = y. oThe equation then becomes y = a sin bx. The graph is consequently the same as in Ex. 2, the effect of the term+ c being merely to shift the origin. Ex. 4. y = a cos bx.This may be written y = a sin (bx + which is a curve of Ex. 3. Hence the graph of the cosine… … 4- sin 2x sin x + -jsin 2xy=sinx 1l-K, that is, when x — — i where A- is any integer. Hence sin 2 x, asshown in fig. 53. Ex. 6. y = si w = 0 when - the graph crosses the axis of x at the points 1, h, \, \, £, etc. Between anyconsecutive two of these points y varies continuously from 0 to ± 1 and…
