How do you find the sine of an angle?
In any right angled triangle, for any angle:
- The sine of the angle = the length of the opposite side. the length of the hypotenuse.
- The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.
- The tangent of the angle = the length of the opposite side. the length of the adjacent side.
Why is sin 30 and cos 60 equal?
Answer. According to the property of cofunctions (Topic 3), sin 30° is equal to cos 60°.The sine is the ratio of the opposite side to the hypotenuse.
How do you find COT 30 degrees?
⇒ 30 degrees = 30° × (π/180°) rad = π/6 or 0.5235 . . . Explanation: For cot 30 degrees, the angle 30° lies between 0° and 90° (First Quadrant). Since cotangent function is positive in the first quadrant, thus cot 30° value = √3 or 1.7320508. . .

Enter your answer, as a simplified fraction. Summary: The exact value of sin 30° is 1/2.
Is the value of sin 60?
From the above equations, we get sin 60 degrees exact value as √3/2.
What fraction is cos 30?
√3/2
Cos 30 degrees is written as cos 30° and has a value in fraction form as √3/2. Cos 30° = √3/2 is an irrational number and equals to 0.8660254037 (decimal form).
How do I know if I have SOH CAH TOA?
In this geometry lesson, you’re going to learn all about SohCahToa. It’s probably one of the most famous math mnemonics alongside PEMDAS.
It’s defined as:
- SOH: Sin(θ) = Opposite / Hypotenuse.
- CAH: Cos(θ) = Adjacent / Hypotenuse.
- TOA: Tan(θ) = Opposite / Adjacent.
What is sin 30 degrees in fraction?
Therefore, Sin 30 degree equals to the fractional value of 1/ 2.
What is the value of sine?
As can be seen from the figure, sine has a value of 0 at 0° and a value of 1 at 90°. Cosine follows the opposite pattern; this is because sine and cosine are cofunctions (described later). The other commonly used angles are 30° ( ), 45° ( ), 60° ( ) and their respective multiples.
Is the value of sin 45?
0.7071067812
The value of Sin 45 degree in decimal form is 0.7071067812.
Why is tan 30?
Tangent 30 degrees value is one by root 3 (1/√3). Like Sine and Cosine, Tangent is also a basic function of trigonometry. Most of the trigonometric equation is based on these ratios.
Is Cotangent Cos over sin?
The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x .
What is a 30 60 Triangle?
A 30-60-90 triangle is a special right triangle (a right triangle being any triangle that contains a 90 degree angle) that always has degree angles of 30 degrees, 60 degrees, and 90 degrees.The side opposite the 60° angle will be the middle length, because 60 degrees is the mid-sized degree angle in this triangle.
