What is the equation for COT?
cot (x) = −1 cot ( x) = – 1. Take the inverse cotangent of both sides of the equation to extract x x from inside the cotangent. x = arccot(−1) x = arccot ( – 1) The exact value of arccot(−1) arccot ( – 1) is 3π 4 3 π 4. x = 3π 4 x = 3 π 4. The cotangent function is negative in the second and fourth quadrants.
How to find the cotangent of an angle?
How to Find Cotangent of an Angle? In a right-angled triangle , the COT of an angle can be figured out by taking the ratio of the adjacent side angle and its opposite angle. However, a COT formula to calculate an angle is: Cot (α) = adjacent b / opposite a
When does cot equal 1?
cot (θ) = 1 cot ( θ) = 1. Take the inverse cotangent of both sides of the equation to extract θ θ from inside the cotangent. θ = arccot(1) θ = arccot ( 1) The exact value of arccot(1) arccot ( 1) is π 4 π 4. θ = π 4 θ = π 4. The cotangent function is positive in the first and third quadrants.
How to graph a cotangent function?
Cotangent is the reciprocal of the tangent function. It is an odd function defined by the reciprocal identity cot (x) = 1 / tan (x). The cotangent graph can be sketched by first sketching the graph of y = tan (x) and then estimating the reciprocal of tan (x). It has the same period as its reciprocal, the tangent function.
