Cos 1 Math

Cosecant secant and cotangent.

Cos 1 math. Arcsin y is the same as sin 1 y atan θ is the same as tan 1 θ etc. Cosec x 1 sin x cot x 1 cos x tan x sin x. Trig calculator finding sin cos tan cot sec csc to find the trigonometric functions of an angle enter the chosen angle in degrees or radians. Underneath the calculator six most popular trig functions will appear three basic ones.

Remember you cannot divide by zero and so these definitions are only valid when the denominators are not zero. Note sec x is not the same as cos 1 x sometimes written as arccos x. The value of the inverse cos of 1. Sine cosine and tangent and their reciprocals.

The inverse cos of 1 ie cos 1 1 is a very special value for the inverse cosine function remember that cos 1 x will give you the angle whose cosine is x. As you can see below the inverse cos 1 1 is 0 or in radian measure 0. We have additional identities related to the functional status of the trig ratios. Sine cosine and tangent often shortened to sin cos and tan are each a ratio of sides of a right angled triangle.

Sine cosine and tangent. If sec x 2 cos x x 60º. Math explained in easy language plus puzzles games quizzes worksheets and a forum. For a given angle θ each ratio stays the same no matter how big or small the triangle is.

Divide the length of one side by another side. Note that the three identities above all involve squaring and the number 1 you can see the pythagorean thereom relationship clearly if you consider the unit circle where the angle is t the opposite side is sin t y the adjacent side is cos t x and the hypotenuse is 1.
