sir, why the arguement of complex no:,z=i-1/cos60 + isin60 is 75
Asked by | 06 Mar, 2013, 08:46: AM
Expert Answer
amplitude will not be 75 for the question
Z=i-1/cos60 +isin60
=-2+(1-√3/2)i
as x is negative and y is positive so complex no. will lie in second quadrant
amplitude will be=∏-tan^-1[(2-√3)/4}
