Find zw and N|3 W z=2 cos Write each answer in polar form and in exponential form. 2x 9 + i sin * w=4 cos + i sin 2x 9 The product zw in polar form is and in exponential form is. (Simplify your answer. Type an exact answer, using as needed. Use integers or fractions for any numbers in the expression.)
For the following vectors, (a) find the dot product vw; (b) find the angle between v and w; (c) state whether the vectors are parallel, orthogonal, or neither. v=81+5j, w=51-8j (a) v w = (Simplify your answer.) CH
