Trigonometric graphs help us understand how certain things behave over time. They are especially useful for showing periodic events, which are things that repeat in a cycle. Here are some important terms related to these graphs:
Amplitude: This is the highest point of the wave from the middle line. For example, amplitude can tell us how tall ocean waves get or how loud sounds can be.
Period: The period is how long it takes to complete one full wave. In simple terms, for sine and cosine waves, this is radians or . It can show us patterns that repeat in a day, like changes in temperature or how long the sun is out.
Frequency: Frequency tells us how many cycles happen in a certain amount of time. For example, if a wave has a frequency of 1 Hz, it means it completes one cycle every second. This is really important for sounds, where pitch is affected by how often the waves happen.
Phase Shift: Sometimes, the graphs of these functions are moved left or right. This phase shift can show delays in events that repeat, like the phases of the moon or when the tides come in and out.
In areas like engineering and physics, trigonometric functions are great for modeling waves, movements, and rotations. They help us understand repeating patterns that we see in nature and in technology, making them very useful in things like sound design and electrical engineering.
