Q. Express z1=6+23i in polar form.Express your answer in exact terms, using degrees, where your angle is between 0∘ and 360∘, inclusive.z1=
Identify rectangular coordinates: Identify the rectangular coordinates of the complex number.The complex number z1=6+23i has a real part (x-coordinate) of 6 and an imaginary part (y-coordinate) of 23.
Calculate magnitude: Calculate the magnitude (r) of the complex number.The magnitude is given by r=x2+y2.For z1, r=62+(23)2.r=36+12.r=48.r=43.
Calculate argument in radians: Calculate the argument (θ) of the complex number in radians.The argument is given by θ=arctan(xy).For z1, θ=arctan(623).θ=arctan(33).Since arctan(33) corresponds to 6π radians, we have θ=6π.
Convert argument to degrees: Convert the argument from radians to degrees.θ in degrees is given by θdeg=θ×π180.For z1, θdeg=6π×π180.θdeg=30∘.
Express in polar form: Express the complex number in polar form.The polar form of a complex number is given by r(cos(θ)+isin(θ)).For z1, the polar form is 43(cos(30∘)+isin(30∘)).
