Cot A Math
Cot ฮธ equals or.
Cot a math. These six trigonometric functions in relation to a right triangle are displayed in the figure. The circle definition a generalization of sohcahtoa is shown below on the right. For example the triangle contains an angle a and the ratio of the side opposite to a and the side opposite to the. In a right triangle the cotangent of an angle is the length of the adjacent side divided by the length of the opposite side.
In a formula it is abbreviated to just cot. The trig function cotangent written cot ฮธ. For acute angles cot ฮธ can be found by the sohcahtoa definition shown below on the left. Note sec x is not the same as cos 1 x sometimes written as arccos x.
Cot x 1 cos x. If sec x 2 cos x x 60ยบ. Of the six possible trigonometric functions cotangent secant and cosecant are rarely used. Graphs of sec x and cosec x.
Remember you cannot divide by zero and so these definitions are only valid when the denominators are not zero. Tan x sin x. Sin cosine cos tangent tan cotangent cot secant sec and cosecant csc.
