How would you graph r = -2sec( Θ - 11π/6 ) ?

OpenStudy (wach):

Well, let's first look at what the sec graph looks like and see each of the components.

OpenStudy (anonymous):

is -2 the radius?

OpenStudy (wach):

F(t) = Af(Bt – C) + D where A: amplitude is A B: period is (2π)/|B| C: phase shift is C/B D: vertical shift is D

OpenStudy (wach):

-2 is the amplitude, ie how much the graph goes up and down.

OpenStudy (anonymous):

r = secΘ is a line

OpenStudy (wach):

Trig function, right? I'm sort of confused about what you mean, but here is a site explaining how to get to the sec graph from cos. You then apply the components like amp, period, etc, to get the resultant.

heh, poler equation
