Solve this formula for r. Simplify your answer. E/d=R+t/r
Make sure you use parenthesis around any polynomials in the numerator and or denominator.
E/d = R + t/r
multiply through by dr:
Er = Rdr + td
(E-Rd)r = td
r = td/(E-Rd)
Make sure you use parenthesis around any polynomials in the numerator and or denominator.
multiply through by dr:
Er = Rdr + td
(E-Rd)r = td
r = td/(E-Rd)
