Cot Is Math

Cot θ adjacent opposite.

Cot is math. For example csc a 1 sin a sec a 1 cos a cot a 1 tan a and tan a sin a cos a. Remember you cannot divide by zero and so these definitions are only valid when the denominators are not zero. The tangent function tan θ opposite adjacent see. It is the length of the adjacent side divided by the length of the side opposite the angle in a right angled triangle.

In a formula it is abbreviated to just cot. Secant cosecant and cotangent almost always written as sec cosec and cot are trigonometric functions like sin cos and tan. The trig function cotangent written cot θ. Of the six possible trigonometric functions cotangent secant and cosecant are rarely used.

Cot θ equals or. Cot x 1 cos x. Sec x 1. F x cot x is a periodic function with period π.

Based on the definitions various simple relationships exist among the functions. The six trigonometric functions. Note sec x is not the same as cos 1 x sometimes written as arccos x. For acute angles cot θ can be found by the sohcahtoa definition shown below on the left.

The circle definition a generalization of sohcahtoa is shown below on the right. In a right triangle the cotangent of an angle is the length of the adjacent side divided by the length of the opposite side.
