    On any HP48S[X] or HP48G[X]:

    In: 'c^2=a^2+b^2-2*a*b*COS(C)' 'C' ISOL
    Out: 'C=ACOS((a^2+b^2-c^2)/(2*a*b))'

    In: 'c^2=a^2+b^2-2*a*b*COS(C)' 'b' QUAD
    Out: 'b=(-(2*a*COS(C))+s1*\v/((2*a*COS(C))^2+4*(c^2-a^2)))/-2'

    In: RAD 'x=COS(x)' 'x' 0 ROOT
    Out: .739085133215

    For Erable and ALG48 (by the 49 series CAS authors), CAS48, etc.:
