This resource includes notes on how to evaluate trig functions given two different scenarios. I teach this lesson directly after my students discover the CAST/ASTC method.

• Steps on how to evaluate all 6 trig functions given a coordinate.
• 2 practice problems with being given a coordinate.
• Steps on how to evaluate all 6 trig functions given a trig ratio.
• 3 practice problems with being given a trig ratio.
• 2 practice problems where students determine which quadrant to draw a triangle in given parameters.
• The practice problems also include radicals and rationalizing denominators.

An answer key is included.

Need notes on more trig? Additional resources are available in the store!

There is also a colorful CAST/ASTC poster in my TPT store that you can print out for students or print as a big poster for your classroom/word wall.

Enjoy!
