What is the gradient of a sine curve?
Cosine
How are sine and cosine curves similar?
The sine curve is exactly the same as the cosine curve shifted pi/2 radians to the left
What is continually changing in the sine curve?
The angle.
What is the connection between trigonometry ratios and sound waves?
Sound waves are transmitted through a medium as variations in the pressure of the medium. If the variation is plotted as a function of distance (or time), they will generate a sine curve (the cosine curve is the same as a sine curve with a phase shift). In practise, the sine curve is damped: the amplitude (or height) of the oscillations gradually decrease over time or distance, because of attenuation.
What happens to a sine curve if a negative constant c is added to the variable x?
The curve is shifted to the right by c.

Sine wave means what?
The sine wave is also called a sinusoid is a mathematical curve that describes the smooth repetitive oscillation.
How do you convert a sine curve function to a cosine curve function?
One way is to shift it to the left by a quarter of the period.
What happens to a sine curve if a negative constant c is added to the variable x?
The curve is shifted to the right by c.
How do you shift a sine wave up or down?
You can move a sine curve up or down by simply adding or subtracting a number from the equation of the curve. For example, the graph of y = sin x + 4 moves the whole curve up 4 units, with the sine curve crossing back and forth over the line y = 4. On the other hand, the graph of y = sin x - 1 slides
If you are given the equation of an normal sine curve how would you determine its period?
a normal sine curve exists with the formula Asin(Bx+C)+D. The formula to derive a phase shift would be such: 2pi/B (for whatever value B exists at). Thus, for a normal sine curve (sin(x) we would get 2pi/1, and arrive at 2pi for the period.
A wave traced by the motion of a pendulum above a moving surface is a?
Sine curve
How do you find amplitude in trigonometry?
The amplitude of a sine (or cosine) curve is the difference between the maximum and minimum values of the curve, measured over a whole cycle.
