Tips / Samples
I started with the topic in the title. In the top box I typed the types of problems we can solve that fall under this topic. We then determine if we are looking for a side length or a missing angle measurement in the next level. We then need to decide which relevant information we have on the next level. We then need to align that information with the appropriate trig function. We can then use the correct function to solve the problem.
Trigonometric functions can be used to solve unknown lengths and angle measures in right triangles.
What sides and angles do I know?
What side or angle am I looking for?
Am I working with the adjacent and the hypotenuse?
Am I working with the opposite and the adjacent?
Am I working with the opposite and the hypotenuse?
If I'm looking for a side I use the approrpiate trig function.
If I am looking for an angle I use the appropriate inverse trig function.
Solve for the desired unknown.
