What quadrant is sin 60 in?
The related angle is 60°. | |
---|---|
120° is in the second quadrant, | |
so sin 120° | = sin 60° |
= . |
What is sin 60 degrees in radians?
To convert degrees to radians, multiply by π180° π 180 ° , since a full circle is 360° or 2π radians. The exact value of sin(60) is √32 .
How do you find cos 60?
The value of cos 60 degrees can be calculated by constructing an angle of 60° with the x-axis, and then finding the coordinates of the corresponding point (0.5, 0.866) on the unit circle. The value of cos 60° is equal to the x-coordinate (0.5). ∴ cos 60° = 0.5.
What is COS 60 as a fraction?
1/2
The value of cos 60 is 1/2.
Is sin 60 negative?
Trigonometry Examples Make the expression negative because sine is negative in the fourth quadrant. The exact value of sin(60) is √32 .
How do you write cos 60?
The value of cos 60 degrees is 0.5. Cos 60 degrees in radians is written as cos (60° × π/180°), i.e., cos (π/3) or cos (1.047197. . .)….Using trigonometry formulas, we can represent the cos 60 degrees as:
- ± √(1-sin²(60°))
- ± 1/√(1 + tan²(60°))
- ± cot 60°/√(1 + cot²(60°))
- ±√(cosec²(60°) – 1)/cosec 60°
- 1/sec 60°
What are the sine and cosine values of a 60 angle?

What is COS 60 in a triangle?
The value of cos 60 is 1/2. Trigonometry is used to study the measurements of right-angled triangles that deals with the parameters such as length, height and angles of the triangle.
How do you find cosine 60?
What is the value of sin 60 in an equilateral triangle?
(Topic 2, Problem 6.) In an equilateral triangle each side is s, and each angle is 60°. Therefore, A= ½ sin 60°s2. Since sin 60° = ½,
What is the cotangent of sin 60?
The sine is the ratio of the opposite side to the hypotenuse. sin 60° = 2 = ½. Lesson 5 of Algebra The tangent is ratio of the opposite side to the adjacent. tan 60° = 1 Problem 2. Evaluatecot 30° and cos 30°. The cotangent is the ratio of the adjacent side to the opposite. Therefore, on inspecting the figure above, cot 30° =
What is sin 60 degrees in trigonometry?
Sin 60 Degrees In trigonometry, there are three major or primary ratios, Sine, Cosine and Tangent, which are used to find the angles and length of the right-angled triangle. Before discussing Sin 60 degrees, let us know the importance of Sine function in trigonometry.
What is the value of sin 30 in a triangle?
Since the sum of all angles in a triangle is 180 degrees, and one of them is 60 degrees within the right-angled triangle, thus the angles in the triangle are 90 degrees, 60 degrees, and 30 degrees respectively. Now, we all know that sin 30 = 0.5 = 1/2.
