The curve C has the parametric equations
x=acosty=bsin2t0≤t≤π2 x = a \cos t \quad y = b \sin 2t \quad 0 \leq t \leq \frac{\pi}{2} x=acosty=bsin2t0≤t≤2πwhere a a\,a and b b\,b are positive constants.
The curve meets the x x\,x axis at (0,0)(0, 0)(0,0) and (6,0)(6, 0)(6,0). Find the value of aaa
The area between the curve and the x x\,x axis is 16. Find the value of bbb
