This graphical representation confirms the negative value observed in the second quadrant. Taking the reciprocal of this fraction results in the exact value of -√2.
Sec 135 Degrees Common Mistake Alert: Avoid These Pitfalls
Graphical Representation and Unit Circle Context Visualizing sec 135 degrees on the unit circle clarifies its geometric interpretation. For instance, the tangent of 135 degrees is -1, as the sine and cosine values are equal in magnitude but opposite in sign.
Another frequent mistake is incorrectly identifying the reference angle; it is vital to subtract the angle from 180° to get 45°, rather than adding or subtracting incorrectly. Consequently, the cotangent also equals -1.

The x-coordinate of this point represents the cosine, and the secant value is determined by the length of the segment that extends from the origin to the intersection of the terminal arm and the vertical tangent line at (1,0). Understanding sec 135 degrees requires looking at its position within the Cartesian coordinate system, where it resides in the second quadrant.
