Evaluate Arctan 1. Consequently, arctan 1 is the unique number in the interval ( − π / 2, π / 2) whose sine and cosine are equal. For a contraction, the (sufficient) condition you state would require \alpha < 1.

I.e., It Is In Particular 1.
Since tan π/4 = tan 45º = 1 the arctangent of 1 is equal to the inverse tangent function of 1, which is equal to π/4 radians or 45 degrees: Arctan (tan (x)) = x, for all x in (, ) these properties allow us to evaluate the composition of trigonometric functions. Θ = arctan(1) is the angle θ ∈ ( − π 2, π 2) satisfying tan(θ) = 1.
