## What has a period of 2pi?

The functions **sin x and cos x** both have periods equal to 2π.

**How do you find the period of 2pi B?**

The period of a sine or cosine function is found by the equation **p = 2pi/b** or b = 2pi/p.

**Does sine have a period of 2pi?**

At x> π, sin(θ) goes from 0 to -1 at 3π/2, then back to 0 at 2π. At this point the sin values repeat. **The period of the sine function is 2π**. To graph a more complete graph of y= sin x, we repeat this period in each direction.

**Why is time period 2pi W?**

The constant 2pi comes from the fact that **one revolution per second is equivalent to 2pi radians per second**.

**What formula is 2π?**

The perimeter or circumference of the circle can be found using the equation **C=2π(r)**, where r= the radius of the circle.

**What is a period in math?**

When a number is written in standard form, **each group of digits separated by a comma** is called a period . The number 5,913,603,800 has four periods. Each period is shown by a different color in the place value chart. The period name is written above each period.

**How do you count period numbers?**

Starting on the first day of your last period, just **count out the average number of days between your periods** (aka your average cycle length that you calculated) and that gives you the projected start date of your next period. Voila!

**What does it mean to be 2pi periodic?**

sine and cosine are periodic functions, this means that there exists some positive constant P such that f(s+P)=f(s). for sine and cosine, this constant is 2pi, becuase **their values repeat every 2pi radians**.

**Does CSC have a period of 2pi?**

By contrast, sec and csc are simply the reciprocal functions of cos and sin, meaning that **their periodicity must be 2π**.

**What type of number is 2π?**

Hence, 2π is an **irrational number** andnot rational.

## Where is 2pi on a circle?

There are **2π radians in a full circle**. (So 2π radians should equal 360°. Check it out by multiplying 57.30° by 2π = 6.283.
