WebIf ` 2 sin theta = 2 Build brilliant future aspects You can build a bright future for yourself by taking advantage of the resources and opportunities available to you. WebBecause sine and cosine are periodic, other integer values of k do not give other values. While the n th root of a positive real number r is chosen to be the positive real number c satisfying c n = r, there is no natural way of distinguishing one particular complex n th root of a complex number. Therefore, the n th root is a n-valued function of z.
