__ **Mar 5 2013** __ Thin line y=sinx; Thick line y= sin(1.5x) or sin (3/2*x). See the behavior of the two graphs? What is your observation?

y= -5 + 2sin(1.5x+pi) - (1)

Question was : (pi/2,1) lies on y=sinx. Where is that coordinate in the equation (1) ?

What is the vertical shift? What is the horizontal shift? What is the amplitude?

Translations of Sine and Cosine Functions




 * Function : is a relationship between two variables in which one variable is matched uniquely to the other.**

Use the ** VERTICAL LINE TEST ** to see if they only intersect at ONLY ONE point. Observe that in those trig functions that have asymptotes. the asymptotes are excluded from the domains.
