SP#7: Unit Q Concept 2: Finding All Trig Functions When Given One Trig fFunction and Quadrant

This SP7 was made in collaboration with Mason Nguyen.  Please visit the other awesome posts on their blog by going here

Using Identities

Using SOHCAHTOA

 The viewer must pay special attention to identifying which quadrant the triangle is in. This is crucial because it determines which trig functions will be positive and which ones will be negative. Additionally, it is important to pay attention to the denominator, there cannot be a radical in the denominator, it must be rationalized. Lastly, the viewer should be able to recognize that the trig functions were solved in two ways, through the use of identities and  SohCahToa, these two methods resulted in the same correct answers! :)
