Investigating the Idea of Tan
Fifth graders use tan to solve problems involving right-angled triangles. They solve equations of the form tan(8) =a, for a between 180 degrees and 360 degrees. They state the value of tan (8) in special cases.
Curated OER
What is s and t?
Learners formulate and solve various types of equations. They become familiar with different types of patterns and apply the knowledge to solving mathematical problems from analyzing them.
