Answers

Answered by ankanbanerjee2005

Answer:

Tan is negative in the second and fourth quadrant, that is between the angles Pi/2 and Pi (second quadrant) and between the angles 3pi/4 and 2Pi (fourth quadrant). For theta = pi/4 (45 degrees) the tan of the angle is 1. For tan to be -1, the angle would be (Pi - Pi/4) and (2Pi - Pi/4).
