Learn how to write the trigonometric equation of a graph step by step by identifying the key features that shape sine and cosine functions. You’ll see how to find the amplitude, period, midline, phase ...

Learn how to solve trigonometric equations. There are various methods that can be used to evaluate trigonometric identities, they include by factoring out the gcf and simplifying the factored equation ...

Let's remind ourselves of what the sine graph looks like so that we can see how many solutions we should be expecting: Therefore, from the graph of the function, we can see that we should be expecting ...

Many students think they've solved a trig equation when they get one answer (one size of angle \(x^\circ\)). However there's often more than one answer expected so be aware of this. Let's remind ...
