Webb(Edit): Because the original form of a sinusoidal equation is y = Asin (B (x - C)) + D , in which C represents the phase shift. So, here in this case, when our sine function is sin (x+Pi/2), comparing it with the original sinusoidal function, we get C= (-Pi/2). Hence we will be doing a phase shift in the left. WebbYou mat say that sin (a)/sin (b) = 2*sin (a/2)*cos* (a/2)/ (2*sin (b/2)*cos (b/2) = tan (a/2) * cot (b/2). This may be useful in some problems, but that is about it. 2 BowTangey PhD in …
