Do you understand what each of A, B, C and D do in the general form \(\Large y=A\sin[B(x-C)]+D\) ? Your text might use different letters, but you should understand how A, B, C and D affect the sine function (and similarly for tangent and cosine - just replace the function name).

|A| gives you stretches/shrinks, and if A<0 you get a reflection over the x-axis B gives you a period change, where the period for sine and cosine = \(2\pi/B\) and for tangent period =\(\pi/B\) Also if B<0, then you get a reflection over the y-axis. C gives you a horizontal shift, to the right if C>0 and to the left if C<0. D gives you a vertical shift, up if D>0 and down if D<0.
