Find the product z1&z2 and the quotient (z1/ z2) . Express your answers in polar form. z1= square root(2)(cos(85degrees)+i sin(85degress)), z2= 4 square root(2) (cos(70degress) +i sin(70degress))

Answer 1

Determine z₁ and z₂ in polar form (I have provided two solutions previously)

(z₁)(z₂) = ||z₁|| ||z₂|| [cos (θ₁ + θ₂) + i sin (θ₁ + θ₂)] This is a formula

(z₁) / (z₂) = ||z₁|| / ||z₂|| [cos (θ₁ - θ₂) + i sin (θ₁ - θ₂)] Also a formula
