Lesson Summary: By the end of this lesson, you should be able to convert degrees into radians and vice versa while understanding how they pertain to the chart created in the previous lesson. In the next lesson, your understanding of the importance of radians in trigonometry will only increase as you will ultimately understand their significance in pertinence to the unit circle and in pre-calculus and beyond as we will be working solely in radians, making them become second nature.
