Given : z=1+3i

To Find :  Modulus

Solution:

 z=1+3i

Modulus  z = | z |  

= √1² + 3²

= √1 + 9

= √10

Modulus  of =1+3i  =  √10

amplitude of z = arg z =  Tan⁻¹( 3/1)

=>amplitude of z =   Tan⁻¹( 3)

=>  Tan⁻¹( 3) =  71.565°  or 1.249 rad

amplitude of 1+3i  =  1.249   ( as its measured in radian )
