If Z = A sin ⁡ θ + B cos ⁡ θ A + B ; then

Question

If Z = A sin ⁡ θ + B cos ⁡ θ A + B ; then, the dimensions of Z and A are the same, the dimensions of Z and B are the same, Z is dimensionless quantity, none of these

MARKS App · Accepted Answer

Z = A sin ⁡ θ + B cos ⁡ θ A + B ; Dimensions of A and B would be same as two quantities can be added only when they have same dimensions. So from given equation, we can say that Z is dimensionless.
