After students have had time to determine the measures and check answers with their partner, the teacher can choose students to post solutions on the board. Instructional Plan Objectives + Standards Materials Assessments + Extensions Questions + Reflection Related Resources Print All Prior to this lesson, it is likely that students have only used trigonometry to solve problems involving right triangles
Spherical Law of Cosines Back to Top Spherical trigonometry involves the study of spherical triangles, which are formed by intersection of three great circle arcs on the surface of the sphere. This formula allows usTo determine the side distance end to end of non-right triangle as long as you know two sides and an angle.To determine any angle of a triangle if you identify all three side lengthsThe law of cosines formula expresses the following associations between the sides angles of any triangle
The Laws of Sines and Cosines Made Simple!
This activity can be extended by having students draw their own triangles, trade papers with other students and calculate the missing parts of these triangles. This gives some groups problems that are quite difficult and require higher level thinking to solve.) Have students trade papers with each other, or with other groups
The amplitude and period of sine and cosine functions involves the distance from the midpoint to the highest or lowest point of the function and the distance between any two repeating points on the function. Fourier Sine and Cosine Series Back to Top A fourier series is essentially a means of expressing any periodic function as a sum of sines or cosines of different frequencies
During this lesson, students will discover how the law of cosines can be used to solve problems involving non-right triangles for which the law of sines cannot be used. Explain to students that during this activity, they will develop the law of cosines, which addresses the cases of triangles for which the law of sines cannot be used
