Cos -30

Since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. Example 2. Evaluate sin 30°. Answer. According to the property of cofunctions (Topic 3), sin 30° is equal to cos 60°. sin 30° = ½. You can see that directly in the figure above. Problem 1. Evaluate sin 60° and tan 60°.

cos(number);. Parameter Values. Parameter Once you prove the cosine and sine formulas, you can divide by them and simplify to get the tangent addition formula, as tan(x) is sin(x)/cos(x), so tan (x+y) PROJECT OVERVIEWGoals and Objectives, Guiding Principles, etc.MASTER PLAN DOCUMENTSAll of the documents ready for downloadProject OverviewThe COS Training Plan.

So, cos(30°) = PO/PH = 6.5/7.5. cos(30°) = 0.8660254037….. Trigonometric Method. By using the cos square identity in trigonometry i.e., cos 2 ϴ = 1 – sin 2 ϴ, we 08.08.2019 cos 10° cos 30° cos 50° cos 70° Yue Kwok Choy 1. Product sum formula Analysis : (a) cos 30° is connected with special angle and should be singled out. (b) You can then combine any two of the three : cos 10° , cos 50°, cos 70° to form a product. Then change this to a sum.

Trigonometry (from Greek trigōnon, "triangle" and metron, "measure") is a branch of mathematics that studies relationships between side lengths and angles of triangles. Cos(30) = 0.154251449888 This is the same answer you will get if you have a scientific calculator set to RAD mode and then enter 30 followed by the Cos button. To find cos of another number, please enter the number below and press "Calculate Cos". The cos of 30 degrees value can be derived mathematically in three methods. One of them is a trigonometric approach and other two are geometrical methods.

See all questions in Trigonometric Functions of Any Angle For cos For memorising cos 0°, cos 30°, cos 45°, cos 60° and cos 90° Cos is the opposite of sin. We should learn it like cos 0° = sin 90° = 1 cos 30° = sin 60° = √3/2 Cos 30 or cos pi/6. In trigonometry, the cosine function is defined as the ratio of the adjacent side to the hypotenuse. Cos 30 value. The value of Cos 30 degree is √3/2 Another Different form of Cos 30° is cos pi/6 or cos π/6 Hence, cos pi/6 = √3/2 . Cos 30° = √3/2 is an irrational number and it equals 0.8660254037 approx. Representing Cos 30°: When the ratio of the base of the reference angle with the hypotenuse is taken, it gives us the cosine value of the ratio at that specific angle.
