LAW OF COSINES

 

The four sided figure consists of two triangles having a common side a.

The law of cosines states that for the top triangle
 
 
 
and a similar equation can be written for the bottom triangle. 

Test Cases

Think of some tests you could devise to check your algorithm.

  • Does your script file pass these tests?

  • Consider that there is a case where there is no correct answer. When does this arise what does your code do in this case?

  • Consider that there is a case where there is more than one correct answer. When does this arise what does your code do in this case?

Develop a procedure forcomputing the length of side c2 if you are given the lengths of sides b1, b2 and c1 andthe angles A1 and A2 in degrees. Write a script file (M-file) to implement this procedure.
