How do you write #-1# in trigonometric form?

1 Answer

Aug 22, 2017

#(r,theta)=color(red)(""(1,pi))#

Explanation:

#-1# in the Complex plane is a point on the negative X-axis (with no "imaginary" component).

The negative X-axis is at an angle of #pi# radians (or #180^@#) from the standard base, the positive X-axis.

#-1# is a distance of #1# unit from the origin and this is what you use as the radius.
