Abstract
Recently approximate solutions to renormalization-group equations were used to calculate the double-power "tricritical" scaling equation of state. We show that this equation can be simply calculated using our exact renormalization-group trajectories. The equation of state is expressed explicitly in terms of nonlinear scaling fields.Keywords
