Plot the complex number on the complex plane and write it in polar form and in exponential form 4-7i Plot the complex number on the complex plane Write the complex number 4 - 7 i in polar form. Select the correct choice below and fill in the answer box(es) within your choice. (Simplify your answer. Type an exact answer for r, using radicals as needed. Type any angle measures in radians, rounding to three decimal places as needed. Use angle measures greater than or equal to 0 and less than 2It.) O A. z= sin + i cos O B. z= cos + i cos D O C. z= sin + i sin O D. z= cos + i sin Write the complex number 4 - 7 i in exponential form. (Simplify your answer. Type an exact answer for r, using radicals as needed. Type any angle measures in radians, rounding to three decimal places as needed. Use angle measures greater than or equal to 0 and less than 21.)
