## How do you find the reference angle of a cot?

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cotangent is negative in the second quadrant. The exact value of cot(60) is 1√3 . Multiply 1√3 by √3√3 .

**What will be the value of tan1350?**

The value of tan is negative in the second quadrant. At the same time tan 135=tan 45. So the value of tan 135=-1.

**What is the reference angle of 150 degrees?**

30°

Looking at a graph, a 150° angle lies in quadrant II, therefore the reference angle is θ’ = 180° – 150° = 30°.

### What is the value of cot?

The value of cot 1 degrees is 57.2899616. . .. Cot 1 degrees in radians is written as cot (1° × π/180°), i.e., cot (0.017453. . .).

**What is the reference angle of 135?**

45′

135′ is in the second quadrant, so our reference angle is 180′-135 “, or 45′ .

**What is the value of cot 45 degree?**

1

Cot 45 degrees is the value of cotangent trigonometric function for an angle equal to 45 degrees. The value of cot 45° is 1.

## What is the reference angle of 240?

60°

Reference angle for 240°: 60° (π / 3)

**What is the reference angle of 330?**

Since 330 is thirty less than 360, and since 360° = 0°, then the angle 330° is thirty degrees below (that is, short of) the positive x-axis, in the fourth quadrant. So its reference angle is 30°.

**What is the reference angle for 135?**

### What is the value of cot (- 870 degree?

1 Answer. = tan 60° = √3 .

**What is a reference angle?**

What is a reference angle. Look at the picture above. Every angle is measured from the positive part of x-axis to its terminal line (the line that determines the end of the angle) counterclockwise. If you want to find the reference angle, you have to find the smallest possible angle formed by the x-axis and the terminal line,…

**What is the reference angle of 10pi/9 in each quadrant?**

Determine the quadrants: 0 to π/2 – first quadrant, so reference angle = angle, π/2 to π – second quadrant, so reference angle = π – angle, π to 3π/2 – third quadrant, so reference angle = angle – π, 3π/2 to 2π – fourth quadrant, so reference angle = 2π – angle. 10π/9 is a bit more than π,…

## How do you find the reference angle of a quadrant?

Determine the quadrants: 1 0 to π/2 – first quadrant, so reference angle = angle, 2 π/2 to π – second quadrant, so reference angle = π – angle, 3 π to 3π/2 – third quadrant, so reference angle = angle – π, 4 3π/2 to 2π – fourth quadrant, so reference angle = 2π – angle.

**What is the reference angle of 480°?**

Find the reference angle of 480°. The reference angle of 480° is 60°. Arithmetic Calculators has a plenty of calculators like trigonometric functions, suppliment and many more. Check them and use whenever required.
