Trigonometric Limits Part 1: An Introduction to Calculus
<p>It’s a helpful way to visualize basic trigonometric functions.</p>
<p>For the rest of this guide, we will be using radian notation, instead of the standard degree one you may be familiar with.</p>
<p>As a reminder, any degree can be expressed in terms of a radian, with the core ratio being that 180 degrees is equal to π radians. With this, you can establish that 60 degrees is π/3 radians, 45 is π/4 radians, ect.</p>
<p>You may already know that the y-values on a point on the unit circle represent cosine and the x-values represent sine, but it is important to build an intuition of why this is for calculus. Later topics require you to have a solid grasp on trigonometry to solve all kinds of problems.</p>
