Accepted Solution

A:

Answer: cot(x) = 3Step-by-step explanation:The cotangent is the reciprocal of the tangent. cot(x) = 1/tan(x) = 1/(1/3) = 3_____It is helpful to memorize the relationships between the trig functions: SOH CAH TOA is a mnemonic that relates triangle sides to trig function values. The remaining relationships you need to know are ... secant = 1/cosine . . . . . . so cosine = 1/secant cosecant = 1/sine . . . . . so sine = 1/cosecant cotangent = 1/tangent . . . . . so tangent = 1/cotangentIt is also helpful to realize that ... tan = sin/cos sin² + cos² = 1 . . . the "Pythagorean" relationship between sine and cosine sec² = 1 + tan² csc² = 1 + cot²
