Question 476790: A sine curve has maximum value 1.5, minimum value -1.5, and period 4 times pie. find and equation for this curve Answer by richard1234(7193) (Show Source):
where A is the "frequency" of the sine function, and 1.5 is the amplitude.. Normally, the function sin x has a period of 2pi, so sin x/2 will have a period of 4pi (graph this if you are unsure), so A = 1/2. B can actually be anything; all B does is shift the graph left or right. So our function should look something like
