Note: This only works when \(x\) is measured in radians. We are now going to look at more complex trigonometric functions where we will use the general rule: \(\int {\cos (ax + b)dx = \frac{1}{ ...

Many students think they've solved a trig equation when they get one answer ... from the graph of the function, we can see that we should be expecting two solutions: one solution being between ...
