Trigonometry
What's the same?
The shape of both graphs (a sinusoidal) is the same as well as the location of the zeroes.
What's different?
The maximum and minimum has changed.
Amplitude: the height above or below the sinusoidal axis, which is the value in front of sine theta.
- Adding a constant will move the graph up or down. The constant will then become the value for your sinusoidal axis.
- If you're going to your terminal side from your initial side (counterclockwise), your angle is positive.
- Going the opposite direction (clockwise), will give you a negative angle.
Co-terminal: when two angles share the same side
