Question

174 A book with many printing errors contains four different formulas for the displacement y of a particle undergoing a certain periodic motion : (a) y = a sin 21 t/T (b) y = a sin ut (c) y = (a/T) sin t/a (d) y = (a/2) (sin 2nt / T + cos 2nt /T) (a= maximum displacement of the particle, v= speed of the particle. T= time-perioa of motion). Rule out the wrong formulas on dimensional grounds. in hoon​
