Write in the \algebraic" form (a+ib) the following complex numbers z = i5 +i+1; w = (3+3i)8: 4. Write in the \trigonometric" form (‰(cosµ +isinµ)) the following ...
Find every complex root of the following. Express your answer in Cartesian form (a + bi): (a) z3 = i. z3 = ei(π +n2π) 2 =⇒ z = ei(π.
The complex number z is given by z = eiθ, − < ≤π θ π . a) Show clearly that 1 n 2cos n z n z + ≡ θ. b) Hence show further that 16cos cos5 5cos3 10cos5θ θ θ θ≡ + + . c) Use the results of part (a) and (b) to solve the equation cos5 5cos3 6cos 0θ θ θ+ + = , 0 ≤ <θ π . 3, , 4 2 4 π π π θ=

Enjoy these free printable sheets focusing on the complex and imaginary numbers, typically covered unit in Algebra 2. Each worksheet has model problems worked out step by step, practice problems, as well as challenge questions at the sheets end. Plus each one comes with an answer key.
Practice. Complex Numbers: Problems with Solutions. Theory. Addition and subtraction of complex numbers: Let (a + bi) and (c + di) be two complex numbers, then: (a + bi) + (c + di) = (a + c) + (b + d)i. (a + bi) - (c + di) = (a - c) + (b - d)i. Reals are added with reals and imaginary with imaginary. Complex numbers multiplication:
