How do you convert #4 (sqrt(3) +i)# to polar form? Trigonometry The Polar System The Trigonometric Form of Complex Numbers 1 Answer A. S. Adikesavan Apr 18, 2016 #8 e^(i(pi/3))=8 ( cos (pi/6) + i sin (pi/6))# Explanation: #x=4sqrt3=y# #x+ i y = r ( cos theta + i sin theta )# #r=sqrt(x^2+y^2)=8# #cos theta = x/r = sqrt3/2, sin theta = y/r=1/2#, Both are positive. #theta# is in the 1st quadrant. #theta=pi/6# So, #4( sqrt3 + i )=8 (cos pi/6 + i sin pi/6 )# Answer link Related questions What is The Trigonometric Form of Complex Numbers?
