i first graphed r=1/sin () + cos ()
from the graph i could see that it formed a right angled triangle wid the x and y axes.
now, i had to figure out the base and height
length of the base can be found be using the trace function. i put theta=0 and i got r=1. that’s my base.
next, i put in theta= pi/2 and i got r=1. which is the height.
then using 1/2 * base * height, i got area = 0.5
