Tan 30 Degrees. The value of tan 30 degrees is 1/√3. The value of tan π/6 can be evaluated with the help of a unit circle, graphically. In trigonometry, the tangent of an angle in a right-angled triangle is equal to the ratio of opposite side and the adjacent side of the angle. Tan 30 degrees is also represented by tan π/6 in terms of radians.

Sec 30. The value of Sec 30 degrees is equal to 2/√3. In trigonometry, you may have learned about three main primary functions, such as sine, cosine and tangent along with them the other three trigonometric functions, such as secant, cotangent and cosecant. Here, you will find the value of sec 30 degrees along with the other secant degree values. .

The inverse cosine function takes a number and gives the angle that has that number as its cosine. There is no (real) angle with a cosine of 30 . 30 . The domain of arccosine is − 1 ≤ x ≤ + 1 . − 1 ≤ x ≤ + 1 . The "arc" functions eat ratios and spit out angle measures. Also, most systems use radian measure by default.Step 4: Determine the value of tan. The tan is equal to sin divided by cos. tan = sin/cos. To determine the value of tan at 0° divide the value of sin at 0° by the value of cos at 0°. See the example below. tan 0°= 0/1 = 0. Similarly, the table would be. Angles (In Degrees) 0°. 30°. Q.

Let A 2 = 30∘ Hence 2A = 60∘. and hence from the above identity we get. cos60∘ = 2cos230∘ − 1. or 1 2 = 2cos230∘ − 1. or 2cos230∘ = 1 + 1 2 = 3 2. Hence cos230∘ = 3 4. and cos30∘ = √3 2. Note we cannot have cos30∘ as − √3 2, as cosine of an angle in Q1 cannot be ...The name cosine comes from the Latin prefix co-and sine function – so it literally means sine complement. And, indeed, the cosine function may be defined that way: as the sine of the complementary angle – the other non-right angle. The abbreviation of cosine is cos, e.g., cos(30°). Important properties of a cosine function:30. The cosine of A relates b to the hypotenuse c, so you can first compute c. Once you know b and c, you can find a by the Pythagorean theorem. 33. You know b and cos B. Unfortunately, cos B is the ratio of the two sides you don’t know, namely, a/c. Still, this gives you an equation to work with: 1/3 = a/c. Then c = 3a.Sec 30. The value of Sec 30 degrees is equal to 2/√3. In trigonometry, you may have learned about three main primary functions, such as sine, cosine and tangent along with them the other three trigonometric functions, such as secant, cotangent and cosecant.
