Explanation:
To convert from
#color(blue)"polar to rectangular form"# That is
#(r,theta)to(x,y)#
#color(orange)"Reminder " color(red)(bar(ul(|color(white)(a /a)color(black)(x=rcostheta , y=rsintheta)color(white)(a/a)|)))# here r = 2 and
#theta=pi/4#
#rArrx=2cos(pi/4)=2xx1/sqrt2=(2sqrt2)/2=sqrt2# and
#y=2sin(pi/4)=2xx1/sqrt2=sqrt2#
#rArr(2,pi/4)to(sqrt2,sqrt2)#
