z = 3i
r=3
theta=taninverse(3/0)=undefine
as we know tan theta is undefine at 90 and 270....check through qustion ..their is + sign with imag part....its mean angle is 90
so we write it as
3(cos90 + isin90)

When z = 8, z lies straight along the real axis, so r = 8 and theta = 0°
you simply differentiate the function and integrate the reamaing trigonometric equation leavin surd form in you ranswer
um... if i was in dat situation i would jus write Mar. and people will understand wat it mean i guess
Meter is usually abbreviated with "m" , so one meter would be 1 m.
