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}{a}} ...

You’re standing at the edge of a cliff, phone in hand, trying to measure the distance to the opposite side – no tape measure, no drone, just your brain. Now what? Trigonometry just became your ...
