What is theta of 6+6i if it is not 45degrees???? I'm kinda stuck. . .

Question

anonymous · Answer

I know the polar form is r(costheta +sin i theta) but I really honestly dont know!!! I know its stupid but I've actually been at these questions for hours straight and I think my brain is fried! Whats even worse is that I have another one thats saying find r and theta of -8-8i as well and I'm just seeing 45degrees everywhere and its not being accepted by the damn computer system ......

And theres no one around to hug me. :(  There should be a warning before you start maths assignments telling you to make sure someone is near you at all times. . . .

Ok...

anonymous · Answer

given z=  6+6i
compare it with z=a+bi we have a= 6 and b= 6
Now $$\theta = \tan^{-1} (\frac{b}{a}) =\tan^{-1} (\frac{6}{6}) =\tan^{-1} (1) =\tan^{-1} (\tan 45^0) =45^0$$
Thus θ= 45 degrees

But i said that the answer was not 45 degrees !!! :/

anonymous · Answer

Your Ans is wrong, it is only 45 degrees.
