Question 11

Write z = 2 + 15i in polar form: r(cosθ + i sin&#952 :wink:

Find the value of z^(1/4) which lies in the secon quadrant of the Aargand diagram and give its argument in degrees

Reply 91

1) r =sqrt229 theta = 82.405356631408555015724136744871

2) r = eighth roots of 229, theta = 110.60133915785213875393103418622

Reply 92

How do you spell 1/8 anyway?

Reply 93

sqrt(229) [ cos 82.4054 + i sin 82.4054 ] (theta in degrees)

r = 1.97233, theta = 110.601 degrees

edited to hell and back... = I lose :frown:

Nope. I'm miles out.

i dont even know anymore!
