Answer:
[A]=[L] ; [c] = [LT^(-1)] ; [D]= [L] ; [b] = [L^(-1)]
Explanation:
Given equation
Note y is displacement whose dimension is [L].
According to dimensional rule,
Dimension of y = Dimension of Asinbx.
We also know sin(x) or any trigonometric function is dimensionless.
Therefore, Dimension of y = Dimension of A
Implies, [y]=[A]. So, [A]=[L]
As angles are also dimensionless
so, dimension of bx = dimensionless
[bx] = dimensionless Or, [b] = [x ^(-1)] = [L^(-1)]
Also, [y]=[c][t]
or [c]=[y]/[t] = [L] / [T] = [LT^(-1)]
And [y] = [D]
Or [D] = [y] = [L]
