Answer: Antenna Radiation The radiation from a transmitting antenna is not uniform in
Chapter 10, Problem 47(choose chapter or problem)
The radiation from a transmitting antenna is not uniform in all directions. The intensity from a particular antenna is modeled by \(r=a \cos ^{2} \theta\).
(a) Convert the polar equation to rectangular form.
(b) Use a graphing utility to graph the model for \(a=4\) and \(a=6\).
(c) Find the area of the geographical region between the two curves in part (b).
Text Transcription:
r = a cos^2 theta
a = 4
