Cot-1

Cot-1, COT-1, cot-1, or cot⁻¹ may refer to:

• Cot-1 DNA, used in comparative genomic hybridization
• cot⁻¹y = cot⁻¹(y), sometimes interpreted as arccot(y) or arccotangent of y, the compositional inverse of the trigonometric function cotangent (see below for ambiguity)
• cot⁻¹x = cot⁻¹(x), sometimes interpreted as (cot(x))⁻¹ = 1/cot(x) = tan(x) or tangent of x, the multiplicative inverse (or reciprocal) of the trigonometric function cotangent (see above for ambiguity)
• cot x⁻¹, sometimes interpreted as cot(x⁻¹) = cot(1/x), the cotangent of the multiplicative inverse (or reciprocal) of x (see below for ambiguity)
• cot x⁻¹, sometimes interpreted as (cot(x))⁻¹ = 1/cot(x) = tan(x) or tangent of x, the multiplicative inverse (or reciprocal) of the trigonometric function cotangent (see above for ambiguity)
