In this lesson on inverse trig functions, the teacher explains that an inverse trig function is not the same as a reciprocal power, and it involves swapping x and y values. The graphs of inverse trig functions are only contained in two quadrants, and they have limited ranges. The teacher demonstrates how to graph the inverse sine function, and how to evaluate expressions involving inverse trig functions by first finding the correct quadrant on the unit circle.
