consider the polar graph §æ =(2/3)¦Ð. (¦Ð=pie)
find the value of N such that r=N§æ, where 0¡Ü §æ ¡ÜN¦Ð has
a)no solution
b)one solution
c)two solution
i think i have figured the first question out.since it's no solution then N must be N<(2/3) because the equation is §æ =(2/3)¦Ð.
but i have no idea how to solve the following two questions!! can someone please help me with this ??
thanks!
