Solving Tan x = -6 on [0, 2π]

The video tutorial explains how to solve the equation Tan x = -6 within the interval from 0 to 2π radians. It discusses the use of the inverse tangent function to isolate x and the necessity of using a calculator to find approximate solutions. The tutorial identifies two solutions within the specified interval, one in the fourth quadrant and another in the second quadrant, and verifies these solutions using a graph of the tangent function.

Why can't we find the tangent of -6 using the unit circle?

• Because the unit circle only shows positive values

• Because the unit circle is only for sine and cosine

• Because -6 is not a valid angle

• Because -6 is not a value on the unit circle
