Any complex number can be written in trigonometric form as
where is the modulus of and is its argument, i.e. the angle makes with the positive real axis in the complex plane.
We have
and
Then
All the angles in a triangle add up to 180 degrees and a right angle is 90 degrees. This leaves 90 degrees and 90-47=43. Angle C=43 degrees

Given:
The sequence is:
To find:
The formula for the nth term in the given sequence.
Solution:
We have,
The given sequence can be written as
The sign are alternative and the absolute value of each term can be defined by the expression , where n is a natural number.
So, the required formula is:
Therefore, the formula for nth term in the given sequence is .
