(4,pi/6)to(2sqrt3,2)(4,π6)(23,2)

Explanation:

To convert from color(blue)"polar to cartesian form"polar to cartesian form

That is (r,theta)to(x,y)(r,θ)(x,y)

color(orange)"Reminder"Reminder

color(red)(|bar(ul(color(white)(a/a)color(black)(x=rcostheta,y=rsintheta)color(white)(a/a)|)))

here r = 4 and theta=pi/6

color(orange)"Reminder"

color(red)(|bar(ul(color(white)(a/a)color(black)(cos(pi/6)=sqrt3/2" and " sin(pi/6)=1/2)color(white)(a/a)|)))

rArrx=4cos(pi/6)=4xxsqrt3/2=2sqrt3 and

y=4sin(pi/6)=4xx1/2=2

Thus (4,pi/6)to(2sqrt3,2)
