WebSep 28, 2024 · tan 135° = tan (90° + 45°) = tan ( (1 × 90°) + 45°) = -cot 45° = -1. Explanation As here too, an odd coefficient of 90° is present, so tan changes to the cot, and also it’s coming to be in the second quadrant where only sine and cosine are positive and rest all are negative. Hence the result of tan 135° = – cot 45° = -1.
