Properties of sine functions
WebSine and cosine are periodic functions of period 360°, that is, of period 2 π. That’s because sines and cosines are defined in terms of angles, and you can add multiples of 360°, or 2 π, and it doesn’t change the angle. Thus, for any angle θ , sin ( θ + 360°) = sin θ, and. cos ( θ + 360°) = cos θ. Many of the modern applications ... WebFeb 13, 2024 · Period and Frequency of Sinusoidal Functions The general equation for a sinusoidal function is: f (x)=±a⋅sin (b (x+c))+d The ± controls the reflection across the x -axis. The coefficient a controls the amplitude. The constant d controls the vertical shift. Here you will see that the coefficient b controls the horizontal stretch. Period
