Suppоse we rоtаte the fixed frаme XYZ tо obtаin a moving frame UVW. First, the fixed frame rotates about the X-axis by 30 degrees, resulting in an intermediate frame X′Y′Z′, with this rotation represented by the matrix Qx. Then, the intermediate frame X′Y′Z′ rotates about its Y′-axis by 60 degrees, producing the final moving frame UVW. This second rotation is represented by the matrix Qy. How can we calculate the resulting rotation matrix Q to represent the transformation between the fixed frame XYZ and the moving frame UVW?
