This circle has the centre at the origin and a radius of 1 unit. The point P can move around the circumference of the circle. At point P the \(x\)-coordinate is \(\cos{\theta}\) and the \(y ...

Watch this video to learn about solving trigonometric equations. Let's remind ourselves of what the sine graph looks like so that we can see how many solutions we should be expecting: Therefore ...

Control and inverse problems in wave equations and graphs are essential areas of research in applied mathematics and engineering. These problems involve determining how to manipulate wave behavior ...
