A complex number may be written in modulus-argument form as
where is the modulus of , and is the argument of .
According to Euler’s relation, the equation is true for any real number . Therefore it is also possible to write a complex number in exponential form as
where again is the modulus of , and is the argument of .
The modulus-argument form of a complex number is . Write that complex number in exponential form.
is another complex number.
