Cos Or Cos 1

Your last sentence is correct. The cos⁻¹(x) is the inverse function to cosine(x). You could say it "undoes" the cosine function, so whereas cosine takes an angle and returns a ratio, cos⁻¹ takes a ratio and returns an angle. You could regard what Sal did as taking cos⁻¹ of both sides, so we'd have cos⁻¹(cos(θ)) = cos⁻¹((19/20) cosecant, secant and tangent are the reciprocals of sine, cosine and tangent. sin-1, cos-1 & tan-1 are the inverse, NOT the reciprocal. That means sin-1 or inverse sine is the angle θ for which sinθ is a particular value. For example, sin30 = 1/2. sin-1 (1/2) = 30. For more explanation, check this out.

Cos Or Cos 1The three main functions in trigonometry are Sine, Cosine and Tangent. They are just the length of one side divided by another. For a right triangle with an angle θ : Sine Function: sin (θ) = Opposite / Hypotenuse. Cosine Function: cos (θ) = Adjacent / Hypotenuse. Tangent Function: tan (θ) = Opposite / Adjacent. The following particularly the first of the three below are called Pythagorean identities sin 2 t cos 2 t 1 tan 2 t 1 sec 2 t 1 cot 2 t csc 2 t Advertisement Note that the three identities above all involve squaring and the number 1 You can see the Pythagorean Thereom relationship clearly if you consider

Beware - the notation cos-1 have two very different meanings: cos-1 (x) = 1/cos (x), i.e., the multiplicative inverse of cos (x); or. cos-1 (x) = arccos (x), i.e., the inverse function of the cosine. In other words, we have the problem of determining the angle whose cosine equals x. We assume that you have in mind the inverse cosine.
