Describe how to use both an equivalent trigonometric identity and a diagram to demonstrate that two trigonometric ratios are equivalent. a) Use one of the following equivalent trigonometric expressions: sin (0+³) cos (0+³7) sin 0 2 tan (0 + ³7 ) 3π = -cot 0 Cos - sin = cot 0 3π sin (3-0) COS (³″ – 0) tan (30) = - = = = = cos b) Using a diagram demonstrate how the related angle formulas are true. Create an example to illustrate your findings in part a) (choose a value for and solve both sides to prove that they are equal.)
