## What is the exact value of sin 240 degrees?

sin (240) = sin (60 + 180) = – sin 60.

**What is cos 240 equal to?**

-0.5

The value of cos 240 degrees is -0.5. Cos 240 degrees in radians is written as cos (240° × π/180°), i.e., cos (4π/3) or cos (4.188790. . .). In this article, we will discuss the methods to find the value of cos 240 degrees with examples.

**How do you simplify sin 240?**

Explanation: For sin 240 degrees, the angle 240° lies between 180° and 270° (Third Quadrant). Since sine function is negative in the third quadrant, thus sin 240° value = -(√3/2) or -0.8660254. . .

### What angle has the same sine as 240?

1 Expert Answer The reference angle for 240 is 60. So the other angle is in quadrant II, with reference angle 60. The angle is 120.

**How do you find tan 240?**

For tan 240 degrees, the angle 240° lies between 180° and 270° (Third Quadrant). Since tangent function is positive in the third quadrant, thus tan 240° value = √3 or 1.7320508. . .

**What is the cot of 240 degrees?**

0.5774

Cot 240 degrees is the value of cotangent trigonometric function for an angle equal to 240 degrees. The value of cot 240° is 1/√3 or 0.5774 (approx).

#### What is the exact value of sin 225?

Trigonometric Function Values of Special Angles

225° | 5π/4 | -√2/2 |

240° | 4π/3 | -√3/2 |

**In what quadrant does 240 degrees lie?**

The Point P(240 Degrees) Is In the Third Quadrant.

**How do you evaluate tan 240 without a calculator?**

## What is the sin of 240 radians?

240 is an obtuse angle since it is greater than 90°. sin (240) = -√ 3 /2. In Microsoft Excel or Google Sheets, you write this function as =SIN (RADIANS (240)) Important Angle Summary. θ°. θ radians.

**How do you find the value of sin 45°?**

From geometry, ∠ABC = ∠BAC = 45°. If BC = k then AB = k. ∴ AB 2 + BC 2 = AC 2 (By Pythagoras Theorem) ∴ k 2 + k 2 = AC 2, or AC 2 =2k 2. ∴ AC = √2 k. Now, sin 45° = sin C= p/h = AB/AC = k/√2 k = 1/√2

**How do you find Sine from sin 150?**

If sin 150° is given to find out, we can write or elaborate this as, Simplify sin 150° into sin (90° + 60°). Now as we have an odd coefficient of 90°, sin changes to cos. Also, it is covering 90° in the first quadrant and again added 60° leads to the second quadrant. In the second quadrant, we know sine is positive.

### What is the value of sin 60 + 180?

Explanation: Trig unit circle –>. sin (240) = sin (60 + 180) = – sin 60.
