What is the amplitude of a trigonometric function?

Back

The amplitude is the maximum distance from the midline of the graph to its peak or trough. It is always a positive value.

How do you determine the amplitude from the equation of a sine or cosine function?

Back

In the equation of the form y = A sin(Bx + C) or y = A cos(Bx + C), the amplitude is given by the absolute value of A.

What is the phase shift of a trigonometric function?

Back

The phase shift is the horizontal shift left or right for periodic functions, determined by the value of C in the equation y = A sin(Bx + C) or y = A cos(Bx + C).

How do you calculate the phase shift from the equation of a sine or cosine function?

Back

The phase shift is calculated as -C/B. If C is positive, the shift is to the left; if negative, the shift is to the right.

What is the vertical shift in a trigonometric function?

Back

The vertical shift is the amount the graph is moved up or down, determined by the value of D in the equation y = A sin(Bx + C) + D or y = A cos(Bx + C) + D.

What is the period of a trigonometric function?

Back

The period is the distance along the x-axis for one complete cycle of the function, calculated as 2π/B for sine and cosine functions.

How do you find the period from the equation of a sine or cosine function?

Back

The period is found using the formula Period = 2π/|B|, where B is the coefficient of x in the function.

What is the difference between sine, cosine, and tangent functions?

Back

Sine and cosine functions represent the y and x coordinates of a point on the unit circle, respectively, while tangent is the ratio of sine to cosine.
