WebWe have to find (√3 + i)1/3. Let z3 = √3 + i = r (cosθ + i sinθ ) Example 2.36 Suppose z1 , z2, and z3 are the vertices of an equilateral triangle inscribed in the circle z = 2. If z1 = 1+ i√3 , then find z2 and z3. Solution z = 2 represents the circle with centre (0, 0) and radius 2. Let A, B, and C be the vertices of the given triangle.

WebAnalysis. This answer looks quite different from the answer obtained using the substitution x = tanθ. To see that the solutions are the same, set y = sinh−1x. Thus, sinhy = x. From this equation we obtain: ey − e−y 2 = x. After multiplying both sides by 2ey and rewriting, this equation becomes: e2y − 2xey − 1 = 0.
