SP: 7 Unit Q Concept 2

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


PROBLEM: tanx= -7/2
sinx>0

The picture above shows various steps on evaluating all the different trig functions when you are only given 2. Follow the steps I have given to understand where each trig function is derived from.

The picture above shows how you can solve the different trig functions when using SOHCAHTOA as the trig ratios.


In order to understand this concept, the viewer must able to recognize all the different trig functions that coexist within one another. Apart from this, the viewer must be able to understand the trig ratios of each trig function so that you can know how the triangle will be pictured as.
