## What is the value of sin Cos Tan?

Values of Trigonometric Ratios at Various Angles:

Angles (in degrees) 60°
Sin θ 0 √3/2
Cos θ 1 1/2
Tan θ 0 √3
Cot θ 1/√3

## What is principal value of sin?

The principal value of sin−1 x for x > 0, is the length of the arc of a unit circle centred at the origin which subtends an angle at the centre whose sine is x. For this reason sin^-1 x is also denoted by arc sin x.

What is the value of sin minus half?

Therefore, the (principal) inverse sine of −12 is −π6 .

### What is the range of sin 1x?

tan−1(x) (−∞,∞) (−π2,π2)
cot−1(x) (−∞,∞) (0,π)

### What is the equation for cos sin Tan?

The functions of sin, cos and tan can be calculated as follows: Sine Function: sin(θ) = Opposite / Hypotenuse Cosine Function: cos(θ) = Adjacent / Hypotenuse Tangent Function: tan(θ) = Opposite / Adjacent

What is tan in terms of sin?

Sin stands for sine, cos stands for cosine, and tan stands for tangent. They are used in trigonometry to find the lengths of sides.

#### How do you calculate the side of a triangle?

According to the Law of Sines, the ratio of the sines of each angle divided by the length of the opposite side are all equal. This helps you to find the sides of the triangle. Add the two angles together and subtract the sum from 180 degrees to find the third angle.

#### How do you calculate sin of right triangle?

Apply the law of sines or trigonometry to find the right triangle side lengths: a = c * sin(α) or a = c * cos(β) b = c * sin(β) or b = c * cos(α)
