- How do you solve tantheta - 4 = 3tantheta - Socratic
See solution below tantheta - 4 = 3tantheta + 4 Let's isolate the theta on one side of the equation -4 - 4 = 3tantheta - tantheta -8 = 2tantheta -4 = tantheta tan is negative in quadrants II and IV Thus, we can conclude the following: theta = 360 - tan^(-1)(4) and 180 - tan^(-1)(4) theta = 284 04^@ and 104 04^@ Below I've placed a diagram to help you represent the signs of the trigonometric
