The exact value of sec 4pi divided by 3 is 1/3.
cos(195) = -0.965925826289
cos20 x cos40 x cos80 = 0.0300 radians = 0.125 degrees (the value for radians is given to four decimal places, the value in degrees is exact)
In a trigonometric equation, you can work to find a solution set which satisfy the given equation, so that you can move terms from one side to another in order to achieve it (or as we say we operate the same things to both sides). But in a trigonometric identity, you only can manipulate separately each side, until you can get or not the same thing to both sides, that is to conclude if the given identity is true or false.
tan u/2 = sin u/1+cos u
There are a few ways. First, there are a multitude of trigonometric tables which list the sines and cosines of a variety of values. if you now one trigonometric value of a number, you can find all the others by hand, and you can also use a Taylor series approximation to find a fairly accurate value. (In fact, many calculators use Taylor series to find trigonometric values.)
sin 0=13/85
A limit in calculus is a value which a function, f(x), approaches at particular value of x. They can be used to find asymptotes, or boundaries, of a function or to find where a graph is going in ambiguous areas such as asymptotes, discontinuities, or at infinity. There are many different ways to find a limit, all depending on the particular function. If the function exists and is continuous at the value of x, then the corresponding y value, or f (x), is the limit at that value of x. However, if the function does not exist at that value of x, as happens in some trigonometric and rational functions, a number of calculus "tricks" can be applied: such as L'Hopital's Rule or cancelling out a common factor.
You find the average rate of change of the function. That gives you the derivative on different points of the graph.
You need to give more information. Please tell me which trig function and which limit and I will be happy to answer your question. Some of these limits exists and some do not.
VLookup( value, table_array, index_number, not_exact_match )value = value to search for in the first column of the table_arraytable_array = two or more columns of data that is sorted in ascending orderindex_number = column number in table_array from which the matching value must be returned. The first column is 1.not_exact_match = determines if you are looking for an exact match based on value. Enter FALSE to find an exact match. Enter TRUE to find an approximate match, which means that if an exact match if not found, then the VLookup function will look for the next largest value that is less than value.this lesson you can find it on grade 5 computer book...
The value of tan A is not clear from the question.However, sin A = sqrt[tan^2 A /(tan^2 A + 1)]
The number of function is Geometry
The exact value of sec 4pi divided by 3 is 1/3.
Range Lookup can be TRUE or FALSE. For your question, you would use the FALSE as the range lookup value. If it is FALSE, then it looks for an exact match only and so it is not necessary to have the values sorted. If it does not find an exact match it will return an error. With TRUE, the values must be in order and either an exact match or the next largest value that is less than lookup value is returned.
what is the value of sin 75 degree
Yes, you could if you knew the exact value for pi as well as the diameter of the circle. Multiply the diameter by the exact value for pi to get the circumference. However, it is impossible because the exact value for pi is not known. It is only known to about a trillion decimal places, but the exact value is not known.
