Step 1

Step 1: First, we need to find the magnitude (r) of the complex number 7-2i using the formula: r = √(a^2 + b^2) where a = 7 and b = -2. Show more…

Convert 7-2i into polar form, r(cos( heta )+isin( heta )) : Use degrees for this problem, not radians. If you're using decimal approximations, you need to be accurate to at least 3 decimal places. Convert 7-2i into polar form,r(cos()+ i sin)): Use degrees for this problem,not radians * If you're using decimal approximations, you need to be accurate to at least 3 decimal places.
