Reminder to learn the exact trig values r/GCSE
1. Evaluate the following. The angle is not commonly found as an angle to memorize the sine and cosine of on the unit circle. 2. Write the expression in terms of common angles. We know the cosine and sine of common angles like and It will therefore be easier to deal with such angles. [2] 3.

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.

0. 0 0. − ∞. -\infty −∞. 🙋 Remember that all trigonometric functions have a periodicity of 2\pi 2π: this means that for every angle \alpha α, the exact calculated value of the trig function f f satisfies the rule: f (\alpha) = f (2k\pi+\alpha) f (α)= f (2kπ +α), where k k is any integer number. Next, you can find the exact value.

Trigonometric Cot Ratios
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
How to Remember the Trigonometric Table 9 Steps (with Pictures)
The trigonometry table is a table of exact values that occur for a specific angle for each of the three trigonometric functions - sine, cosine and tangent. We can use these values to calculate unknown sides, angles and areas of triangles. The table below shows the values of trigonometric ratios of standard angles 0^{\circ}, 30^.

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.

An equilateral triangle with side lengths of 2 cm can be used to find exact values for the trigonometric ratios of 30° and 60°. The equilateral triangle can be split into two right-angled.

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.

Example 1: Finding the Exact Value of the Cosine Ratio Using Radians Find the value of c o s 𝜋 3 . Answer One way we can answer this question is by first converting the angle in radians into one in degrees. We do this by multiplying it by 1 8 0 𝜋. We have 𝜋 3 × 1 8 0 𝜋 = 1 8 0 3 = 6 0 ∘ We can then recall c o s 6 0 ∘. Hence, c o s 𝜋 3 = 1 2.
