let f(x)= arctan(2x)
1) calculate f^((n)) (x) then f^((n)) (0)
2) developp f at integr serie
3) let F(t)= ∫_0 ^t arctan(2x)dx
developp F at integr serie
4) give F(1) at form of serie.
Each of two long straight wires 4cm
apart carry equal electric currents
and experience a force of 2×10^(−4) N/m.
What is the magnitude of the
electric current in each?
Calculate the triple point for an
electrical resistance thermometer,
assuming the ratio of resistance
at the triple point to that at initial
point is 2.0.
