Assessment #2; Comparing Half- Angle & Sum/Difference




We know the answers are the same on both because we confirm it with our calculator. We plug each equation into our calculator and we should get a decimal point. Then we enter the 105 degrees with sine, cosine, and tangent and receive and equivalent decimal from the ones in the  equation. What I got for this particular equation is : Cosine= -.258, Sine= .965, Tangent= -3.732.Thank You for viewing!!
