Question 6 (a) (ii) of this trial paper:
http://www.angelfire.com/ab7/fourunit/hornsby-girls2010.pdf

I got max are occurs when sin 2theta = 1. but then should i have the coordinates of P in both first and second quadrants?
or is it enough to leave it in first quadrant?

edit oops misread post disregard what i said before

for your question, you only use the smaller value of theta to find P because the limits on the question say 0 < theta < pi/2
