2008-08-29 · the exact value is cos(75°). There is no other way to represent the exact value, because the answer is an irrational number. If you want to represent it as a decimal number, you would be writing numbers until the end of time. How to remember exact sin, cos and tan values March 1, 2020 April 30, 2020 samtrapp If you’re studying for your maths GCSE, there are certain values of sine, cosine and tangent that you need to know off by heart. The exact value of $\cos{(30^°)}$ is evaluated theoretically on the basis of this property. The lengths of opposite side and hypotenuse are known but the length of adjacent side is unknown in this case.

How to find the exact value of cos in radians This page is about the functions of sinux, cosine and tangent trigonometrics, what they are and how the exact values of many angles can be found and found. We know that cos (a-b) = cos a * cos b + sin a *sin b cos 15 = cos (45–30) => cos 15 = cos 45 * cos 30 + sin 45 * sin 30 => cos 15 = (1/√2)* (√3/2) + (1/√2 2010-11-23 · There's a pattern that you must memorize, which is the only way to do this. I will tell you that cos(30)= sqrt(3)/2. However, what I think you're asking is a way to actually work it out by writing down a mathematical expression, and unless you're can evaluate infinite term polynomials in your head, this just won't be possible.
