WebThe angle (-x) lies in the 4th quadrant of a graph, and sine is negative in this quadrant. Hence, this shows that tan (-x) = -tan (x). How is tan theta defined? Tan theta of a right … WebNegative Angle Identities Identities also exist to relate the value of a trigonometric function at a given angle to the value of that function at the opposite of the given angle. Here are these identities: sin (- ≈íø) = - sin (≈íø) cos (- ≈íø) = cos (≈íø) tan (- ≈íø) = - tan (≈íø) csc (- ≈íø) = - csc (≈íø) sec (- ≈íø) = sec (≈íø)
Web(iii) In the IVth quadrant, the sign of "tan" is negative.
