 Cosecant, secant, and tangent are inverses of sine, cosine, and tangent respectively, and so they can be found by taking $\frac{1}{x}$, where $x$ is the function you'd like to find the inverse of.
 
+## Angle of Elevation/Depression
+- The **angle of elevation** is the angle between the hypotenuse and the bottom line. As an example, if a ladder was leaning against a building, the angle of elevation would be the angle where the ladder intersects with the ground, and it would be the angle between the ladder and the ground.
+- The **angle of depression** is the angle between the top of the hypotenuse and an (often imaginary) horizontal line.

+# Introduction
+The unit circle has a center a $(0, 0)$, and a radius of $1$ with no defined unit. 
+
+Sine and cosine can be used to find the coordinates of specific points on the unit circle.
+
+**Sine likes $y$, and cosine likes $x$.**
+
+When sine is positive, the $y$ value is positive. When $x$ is positive, the cosine is positive.
+
+$$ cos(\theta) = x $$
+$$ sin(\theta) = y $$
+
+## The Pythagorean Identity
+The Pythagorean identity expresses the Pythagorean theorem in terms of trigonometric functions. It's a basic relation between the sine and cosine functions.
+$$ sin^2 \theta + cos^2 \theta = 1 $$

+# Orthorexia
+Orthorexia is a pattern of disordered eating characterized by a fixation on 'clean eating', or 'perfect eating'. It often begins as a desire to eat only healthy foods but spirals into an obsession. 
+
+Notes from https://www.youtube.com/watch?v=q_mUm8Ow-Dc:
+- Often an emphasis around organic foods.
+- Individuals with orthorexia can go to extreme lengths to prepare meals. 
+- The individual in the video recognizes that he has an issue and is working to fix it.
+- One individual catalogued foods obsessively. 
+- One individual noted that it was becoming a problem when his food choices started consuming so much of his life. 
+- People want to feel like they can make choices that will keep them healthy.
+- Society encourages orthorexia because healthy eating is lauded. 
+- Some individuals stop eating fruits and vegetables they deem to have too high of sugar content.
+- There becomes a fear that if you stop eating healthy, everything will unravel. 
+- "Raw nutritionists" believe that cooking food destroys that food's nutritional value.
+- Deaths have occurred because of orthorexia.
+
+Notes from https://www.youtube.com/watch?v=uPyqCmz8-JQ:
+- Some raw nutritionists meet and talk about how their diet has changed their life.
