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.
