IMLN(Complexnumber)


  • is of the form

Description

  • This function gives the Natural Logarithm of a complex number.
  • In , where Complexnumber is in the form of . i.e & are the real numbers.
  • And is the imaginary unit .
  • Normally Complex logarithm function is an inverse of the Complex exponential function.
  • A logarithm of is a complex number such that and it is denoted by .
  • If with & are real numbers then natural logarithm of a complex number :

adding integer multiples of gives all the others.

  • We can use COMPLEX function to convert real and imaginary number in to a complex number.

ZOS

  • The syntax is to calculate the natural logarithm of a complex number in ZOS is .
    • is of the form
  • For e.g.,IMLN(("10+17i")
Natural Logarithm of a Complex Number
