I keep receiving this syntax error. Anyone have an idea as to why?
WolframLanguage has a units framework!
Try e.g.:
c = EntityValue[Entity["PhysicalConstant", "SpeedOfLight"], "Value"];
speedF35 = Quantity[1200, "Miles"/"Hours"];
Maybe there are some more problems with your code, but I cannot try, because you posted just a picture of code.
gamma[beta_] := 1/Sqrt[1 - beta^2]
c = 299792458 ; (speed of light, m/s)
Mile = 1600 ;(Meter)
Hour = 3600 ;(Second)
speedF35 = 1200.*Mile/Hour;
betaF35 = speedF35/c;
gammaF35 = gamma[betaF35];
SetOptions[SelectedNotebook, PrintPrecision → 30]
Print["Speed of F35 = “, speedF35, " m/s”]
Print["beta of F35 = ", betaF35]
Print["Lorentz factor of F35 = ", gammaF35]
Speed of F35 = 533.3333333333333 m/s
beta of F35 = 1.7790085077234774*10^-6
Lorentz factor of F35 = 1.0000000000015825
Please post actual code rather than images thereof (can use the image to show the error message). Also indicate what you have tried in order to debug the problem.
