A prerequisite to physics is MAT182. Students need to know law of sine/cosine, and vector concepts from trig to be successful in physics. In the past, I would spend a lot of time classify triangles (SSS, ASA, etc) to help students know which "law" to use, and this was done at the end of the semester. I did not spend time using law of sine/cosine with vector applications . Students typically scored a low B on law of sine/cosine problems. In F17, I taught the "laws" and incorporated vectors in week 4 to show students real life applications. I had a "drill/kill" day where students were at the boards solving vector application problems. Zero time was spent classifying triangles. Students had to set up the equations for both "laws", then determine which one was the most useful to solve the triangle. 100% of the students received 5/5 on the law of sine problem. 60% of the students received 5/5 on the vector law of cosine application with the remaining 40% having the correct idea. I will definitely incorporate all these activities in my trig class again.
