Intersection points of the graph its solutions?

  1. Aug 31, 2005 #1
    The graphs of f(theta) = 2sin(theta) - 1 , and g(theta) = 3cos(theta)+2 are given.
    What equation would have the intersection points of the graph its solutions?

    ummm..... what does this mean? and how do i solve it?

    Find the intersection points of f(t) and g(t) and find a function that has those points as solutions (zeros).

    i still dont understand i can find the points where f(t) and g(t) intersect by graphing (how do i do this by graphing?) but what do you mean by having same points as zeros?

    Both of these are the equations of graphs in their polar form.These graph would intersect at some particular point whose position vector will make some THETA angle with the x-axis.To find this particular THETA , solve the above two equations simultaneusly by equation f(Q) and g(Q) and then finding the angle(s).
