Convert each equation from rectangular to polar form. 15) (x + 1) 2 + 1/2 = 1 16) x = y 5 Convert each equation from polar to rectangular form. 17) r = -4cos 0 + 2sin 0 18) tan 0 = 119) r = 3tan Osec 0 20) r = 4sin 0 Two points are specified using polar coordinates. Find the distance between the points. Hint: convert to rectangular coordinates first then use a formula - you know - one that finds distance. 21) ( 2. #1 ) . ( 4 , 3 ) 2) ( 3 , 7 25 ) .
