Write the complex number 8(cos 30 +i sin 30) in standard form?
Hello world!
May 27, 2020CRITICAL THINKING ABOUT THE BIBLE
January 5, 2021You know that (I suppose they are in degrees):
##cos30=sqrt(3)/2##
##sin30=1/2##
So:
##z=8(cos30+isin30)=8(sqrt(3)/2)+i8(1/2)=##
##=4sqrt(3)+4i##
in the form: ##a+ib##
