The amplitude of a sine function represents the maximum distance the wave's graph reaches from its central value (or equilibrium). In general, the sine function can be written in the form y = a \text{sin}(bx + c) Here, the term 'a' is the amplitude. The amplitude is always a positive value, which is obtained by taking the absolute value of 'a'. For instance, in the function y = -2 \text{sin}(x + \frac{\text{\(\frac{\boldsymbol{\boldsymbol{{\frac{\boldsymbol{{{\text{i}}}}}}}{\text{\)\boldsymbol{\text{r}}\(\boldsymbol{{\frac\)\frac{\boldsymbol{\text{\(\frac{{\text{i}}}\) \boldsymbol{\frac\({\boldsymbol{{\frac\)\frac\text{}}\()\) \(\text{}}}b))}}\)}{$$$b}}}{$$$$$$bb\frac\frac)})/33}}$$bb\frac}}\(\frac\)\frac$$ \frac{\text{\( \frac<}e's\)\text{\text{\frac{\frac \(}}}}}}}}\)}\frac{\text{\(}}$$\frac'\frac1)\)\frac\(\text<\)
