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.
Table values for sin 30, cos 30 and tg 30 degrees: That is: The tangent of 30 degrees is equal to the root of three to three A sinus of 30 degrees is equal to one second or 0.5 The cosine is 30 degrees equal to the root of three to two Sine, cosine and tangent angle π / 6 Proceeding from the above-stated principle of translating the radian in
tan 30 = sin 30 / cos 30. tan 45 = sin 45 / cos 45 The value of cos of angle 30 degrees is equal to 3 2 in fraction form exactly. It is an irrational number and equals to 0.8660254037 … in decimal form and the same value is considered as 0.866 approximately in mathematics. The value of cos 30 ° is usually called as trigonometric ratio or function of standard angle in trigonometry. The exact value of cos (30°) is √ (3) / 2. We can find this using the cosine half-angle identity property which is as follows: If an angle, See full answer below.

Trig(3 all with work) 1) Find the 23 Aug 2012 Values of Trigonometric ratios for 0, 30, 45, 60 and 90 degrees. August 23 Hence, all the tan values can be obtained from sin and cos values. tan 0 = sin 0 The values for 360 are the same exact values for 0.
2007-10-24 · Details. The underlying functions newsine and newcosine work by breaking a given angle down into multiples of 90, 30, 15, 3, and 1 degree(s). The values at 3 degrees were found using combinations of 15 and 72 degrees, and the values at 1 degree by using the sine and cosine triple angle formulas and solving the resultant cubics.
