Trig Table Exact Values Awesome Home
What are exact trig values? Exact trig values are the exact trigonometric values for certain angles that you are expected to know for GCSE mathematics. In trigonometry at GCSE there are three trigonometric ratios that we use, sine, cosine and tangent, though we write them as sin, cos and tan.

How to go about learning these special values? Here's the way I do it. How To Remember Trig Values Rather than learn a weird table of numbers and square roots, I find it best to simply remember two triangles. I'll explain them in degrees, you can easily convert into radians if you prefer. Triangle 1
Reminder to learn the exact trig values r/GCSE
Trigonometry For Dummies. The angles used most often in trig have trig functions with convenient exact values. Other angles don't cooperate anywhere near as nicely as these popular ones do. A quick, easy way to memorize the exact trig-function values of the most common angles is to construct a table, starting with the sine function and.

5. Divide your sine values by the cosine values to fill the tangent row. Simply speaking, tangent = sine/cosine. Therefore, for every angle, take its sine value and divide it by its cosine value to calculate the corresponding tangent value. To take 30° as an example: tan 30° = sin 30° / cos 30° = (√1/2) / (√3/2) = 1/√3.

Step 1: Create a table with the top row listing the angles such as 0°, 30°, 45°, 60°, 90°, and write all trigonometric functions in the first column such as sin, cos, tan, cosec, sec, cot. Step 2: Determine the value of sin To determine the values of sin, divide 0, 1, 2, 3, 4 by 4 under the root, respectively. See the example below.

What is Trigonometric Table? The trigonometric table is simply a collection of the values of trigonometric ratios for various standard angles including 0°, 30°, 45°, 60°, 90°, sometimes with other angles like 180°, 270°, and 360° included, in a tabular format.

Next, you can find the exact value.
