Distance Formula

Slope Formula

Slope Intercept Form

How do you represent parallel lines?

By having the same slope in the y intercept form.

How do you represent perpendicular lines lines?

By having the opposite reciprocal slope in y intercept form.

How do you convert radians to degrees?

Multiply by 180/π.

How do you convert degrees to radians?

Multiply by pi/180.

What are the sectors of a circle?

theta = a/r ; a=r*theta

Calculate Theta for a Circle

Theta is calculated using the relationship between arc length and radius, where theta equals the arc length divided by the radius.

theta = a/r

Calculate a for a circle

a=r*theta

How do you draw angles from a standard position?

Angles are drawn from the positive x-axis, rotating counterclockwise for positive angles and clockwise for negative angles.

How do you do even or odd neither function?

Substitute 2 in the x and if it is the oppsite of eachother its odd function. If it is the same, it is even; if neither, it is neither even nor odd.

How do you solve piecewise functions?

To solve piecewise functions, evaluate the function at the given x-value and use the appropriate piece of the function corresponding to that x-value.

How do you determine the domains of functions?

To determine the domains of functions, identify all possible x-values that can be input into the function without resulting in undefined expressions, such as division by zero or square roots of negative numbers.
