Trigonometric Limits Part 1: An Introduction to Calculus

<p>It&rsquo;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 &pi; radians. With this, you can establish that 60 degrees is &pi;/3 radians, 45 is &pi;/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> <p><a href="https://medium.com/@partialderivative/trigonometric-limits-part-1-an-introduction-to-calculus-ba7b1d74c5f9"><strong>Website</strong></a></p>
