Which of the following functions is equal to sin(θ+360°)?
Question
Which of the following functions is equal to sin(θ+360°)?
Solution
The function that is equal to sin(θ+360°) is sin(θ).
Here's why:
The sine function has a period of 360°. This means that the value of the sine function repeats every 360°.
So, sin(θ+360°) is the same as sin(θ) because adding 360° to the angle θ doesn't change the value of the sine function.
In other words, sin(θ+360°) = sin(θ) for any angle θ.
