Chapter 5 Mathematica Commands

1. Sin Cos Tan

Sin["Degree"°]//N

Cos["Degree"°]//N

Tan["Degree"°]//N

Sin[45°]//N

2. Sin Cos Tan with Degree Minute Second

Sin["Degree"°+"Minute"/60°+"Second"/3600°]//N

Sin["Degree"°+"Minute"/60°+"Second"/3600°]//N

Sin["Degree"°+"Minute"/60°+2"Second"/3600°]//N

Sin[23°+58/60°+21/3600°]//N

3. Inverse Sin Cos Tan to Degrees

N[ArcSin["Expr"]/Degree]

N[ArcCos["Expr"]/Degree]

N[ArcTan["Expr"]/Degree]

N[ArcSin[0.9047]/Degree]

0.7829*60

0.974*60

ArcSin[0.9047]=64°46'58"
