## What angles are Coterminal with 3pi 2?

The resulting angle of π2 π 2 is positive and coterminal with −3π2 – 3 π 2 . Since π2 is in the first quadrant, the reference angle is π2 .

**How do you find Coterminal angles?**

Finding coterminal angles is as simple as adding or subtracting 360° or 2π to each angle, depending on whether the given angle is in degrees or radians. There are an infinite number of coterminal angles that can be found.

**Are 3π 2 and Coterminal angles?**

The trigonometric functional values of angles coterminal with 0, π/2 , π, and 3π/2 are the same as those above, and the trigonometric functional values repeat themselves (e.g., π and 3π are coterminal and sin (π) = sin (π + 2π) = sin (3π) = 0). This illustrates the fact that the trigonometric functions are periodic.

### Which angles are Coterminal with each other?

Coterminal angles: are angles in standard position (angles with the initial side on the positive x-axis) that have a common terminal side. For example, the angles 30°, –330° and 390° are all coterminal (see figure 2.1 below).

**What does 3pi 2 equal?**

3pi/2 rad = 270°.

**What is the reference angle for 120?**

60°

Reference angle for 120°: 60° (π / 3)

## What is the Coterminal angle between 0 and 360?

Coterminal angle of 0°: 360°, 720°, -360°, -720° Coterminal angle of 1°: 361°, 721°, -359°, -719°

**What is the Coterminal angle of 120?**

For example, angles measuring 120° and – 240° are coterminal.

**Is 3pi equal to pi?**

### What is the Coterminal angle of?

The coterminal angles are the angles that have the same initial side and the same terminal sides. We determine the coterminal angle of a given angle by adding or subtracting 360° or 2π to it….Coterminal Angles.

**How to find an angle that is coterminal?**

If the given an angle in radians (3.5 radians) then you need to convert it into degrees: Now you need to add 360 degrees to find an angle that will be coterminal with the original angle: Positive coterminal angle: 200.48+360 = 560.48 degrees.

**Which is an angle that has the same initial and terminal sides?**

Coterminal angles are those angles that share the same initial and terminal sides. Their angles are drawn in the standard position in a way that their initial sides will be on the positive x-axis and they will have the same terminal side like 110° and -250°. According to the coterminal definition:

## What is the sin of a 30 degree angle?

A 30 degree angle has a sin of 0.5. This is because a 30–60–90 triangle has a ratio of opposite side over hypotenuse of 1/2. But 30 degrees converts to radians by multiplying by (pi/180). This means 30 x (pi/180) = pi/6. So that is where the 1st answer comes from.
