DeMoivre s Theorem states, If z = r(cos u + i sin u), then zn = rn(cos nu + i sin nu). Verify for n=2?
Q. Ok, the z^2 instead of z2 is really confusing me. Can someone explain why it becomes squared instead of doubled?
Asked by rbot - Thu Jul 23 22:03:11 2009 - - 2 Answers - 0 Comments

A. DeMoivre's Theorem allows you to find powers of complex numbers. Given the complex number z = r(cos u + i sin u) Square both sides, z = r (cos u + 2icos u sin u + i sin u) = r (cos u + 2icos u sin u - sin u) = r [(cos u - sin u) + i(2 sin u cos u)] = r (cos 2u + i sin 2u) So it's true for n = 2.

Q. Thank you for all answers and sorry about the txt speak, there's not enough space!

But my face still has lots of blemishes from spots that I had before and I would like to know how long will these take to fade, 4 weeks seems like forever. Evil spots!! Thank you.

A. Thats why they give you an additional 1000 key strokes to work with inside to further describe your question...because the slang you used is infact, very annoying and hard to read.. But anyway, Im guessing you're young and break outs will happen. wash your face 2-3 times a day with special acne soap. Also buy the acne face pads and whipe your face down whenever you start to get oily, and you should clear up in no time. I use the face pads all the time and my skin is usually always clear. (I have oily skin so if i didnt use them I'd have 5000 zits)

A. Get him some stool softener pills from the drugstore. He probably has not been drinking enough water, and in the warm summertime it is easy to become dehydrated and constipated. Give him some apple juice or other fruit. That will help .My Dr. said there is no danger in not going for up to a week.

A. If you are asking for a voluteer from yahoo then I think it will not be a good choice. I am a fluent speaker of malayalam, and I know how hard it is to learn a new language. Therefore i think that you should get a fluent malayalam speaking tutor and take learn from the tutor. I am telling you this because malayalam is a very difficult language mainly due to its pronouciations, therefore if you hear the tutor speaking, you can get a clearer idea of how the word should sound, because mispronounciations in a word can make it really difficult for the listener to understand. I am really glad to know that you are willing to learn malayalam, it is a really nice but difficult language. Once someone told me that if you can speak malayalam, then… [cont.]

A. Go to sign up or log in and click the link for when you don't have an activation code. You give them your email, your blog address, you give them a first look or a sample look and then say what you would contribtute to the site. If they think you would be a good addition, they will wait for a code to become avaliable and then send it to you. If they don't and it to you, that means they don't think you'd be a good addition. Do not bother to apply if you wear the same thing everyone else does: hollister, etc.

A. "Recall that any complex number can be written in the form r*e^(i*theta). If you plot a complex number in the complex plane (where the x-axis is the real axis and y-axis is the imaginary axis), then "r" will be the distance from the point to the origin and theta will be the angle a line from the origin to the point makes with the x-axis. A little trig shows that a complex number written as r*e^(i*theta) can also be written as r*cos(theta)+r*i*sin(thet a). Knowing this little fact gives us the ability to switch back and forth between ways of writing complex numbers, depending on what we want to do with them. If we want to add complex numbers, then the form a + b*i is easiest, whereas if we want to multiply them together, it is easier to… [cont.]
