How do you find the reference angle for an angle of $$-1035\degree$$ ?

The reference angle is $$45\degree$$ .

How do you determine the period of a cosine function?

The period is determined by the formula $$P = \frac{2\pi}{b}$$ , where 'b' is the coefficient of 'x'.

What is the effect of a negative sign in front of a cosine function?

It reflects the graph across the x-axis.

What is a reference angle?

A reference angle is the acute angle formed by the terminal side of an angle and the x-axis.

How do you find the horizontal shift of a trigonometric function?

The horizontal shift can be found by rewriting the function in the form $$y = a\sin(b(x - c)) + d$$ or $$y = a\cos(b(x - c)) + d$$ .

What is the significance of the phase shift in trigonometric functions?

The phase shift determines how far the graph is shifted horizontally from the origin.

What is the formula to find the amplitude of a sine or cosine function?

The amplitude is given by the absolute value of the coefficient in front of the sine or cosine function.

What does a period of $$\frac{\pi}{6}$$ indicate about the frequency of the sine function?

A period of $$\frac{\pi}{6}$$ indicates a higher frequency, meaning the function completes more cycles in a given interval.

How do you express a sine function that is shifted vertically?

A vertical shift is expressed by adding or subtracting a constant from the function, e.g., $$y = \sin(x) + d$$ .
