To find the amplitude and period of the function (y = \sin(\pi x - \frac{1}{2})):
-
Amplitude: The amplitude of a sine function is the absolute value of the coefficient of the sine term, which in this case is 1. Therefore, the amplitude is (|1| = 1).
-
Period: The period of a sine function is determined by the coefficient of (x) inside the sine function. The formula for the period ((P)) of a sine function (y = \sin(bx)) is (P = \frac{2\pi}{|b|}). In this case, the coefficient of (x) inside the sine function is (\pi). Thus, the period is (P = \frac{2\pi}{|\pi|} = \frac{2\pi}{\pi} = 2). Therefore, the period of the function is 2.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
