SUMMARY
The value of arccot(pi/4) is determined by understanding its relationship to the inverse tangent function. The correct calculation involves recognizing that arccot(x) is equivalent to arctan(1/x). In this case, arccot(pi/4) simplifies to arctan(0.7854), yielding a value of approximately 0.905, as confirmed by WolframAlpha. Misinterpretation of the unit circle led to confusion, as the tangent of pi/4 equals 1, not the arccotangent.
