    @amber12362 Both are great tools, but I need to know how to graph without the use of them. :)

    |dw:1437268324013:dw| now the period is 3pi/2 ...to get the size of the quadrant we take the period and divide by 4 ..so 3pi/2 divided 4= 3pi/8 this would be our 1st quadrant and we kept adding 3pi/8 to get the 2nd and 3rd and 4th what i mean: 3pi/2 divided by 4= 3pi/8 now 3pi/8 + 3pi/8=3pi/4 3pi/4+3pi/8=9pi/8 then 9pi/8+3pi/8= 3pi/2...do u see here we get back our period for the graph?? ...and since we know that the normal period for a cos function is 2pi..it means that it the stink ..lol
