find, at how many points do both the graphs intersect.
these are for 0 to 180.
now multiply the no. of roots by 2
and you get the answer for 0 to 360

means the answer is 4?

i don't know, i didn't work it out.
if there are 2 solutions for 0 to 180
then yes , the asnwer will be 4

okay thank you.

Can anybody tell me the method to find area of a quadrilateral other than that of matrix one??

No the answer is 2 because from 180 to 360 the two graphs do not meet at all.
