### How does it work?

Option 1: Just fill in the form with your homework question, and someone will respond shortly with an answer.

Option 2: Take a photo (or link) of your question, and email or text it to us.

### Like us? A: A radian is the angle measured between radii of a circle which are subtended by an arc which has the same length as the radii.

It may be easier to remember: a radian is just another measure of an angle, just like degrees.

## Graphing Trig Functions

Q: How do I graph trigonometry functions?

A: Always picture the regular graphs of y=sin(x) and y=cos(x) and then apply each of the transformations to those original graphs.

The amplitude of each graph is 1, and the period is .

The general equation for a sine graph is: . . . → Read More: Graphing Trig Functions

## Graphing Trig Functions, y=3sin(x) + 4

Q: How do I graph y=3sin(x) + 4?

A: Remember that the standard form for a trigonometric equation is:

y=A*sin(B(x-C)) + D

In your case A=3, B=1, C=0 and D=4

The A=3 term means that the graph is stretched vertically 3 units. B=1 and C=0 mean that the period of the graph is . . . → Read More: Graphing Trig Functions, y=3sin(x) + 4
