The serial manipulator shown in figure 1 (in the attachment) is set in a configuration such that the pose of the effector with respect to a world reference frame, Rworld, is defined by the composed homogeneous transformation matrix, Qgripper/world, that follows (defined with respect to evolving reference frames):

{Please refer to the attachment for the matrix.}

On the other hand, the pose of the robot base with respect to the world reference frame, Rworld, is defined by the composed homogeneous transformation matrix, Qbase/world, that follows (defined with respect to evolving reference frames):

{Please refer to the attachment for the matrix.}

Moreover, the Denavit-Hartenberg parameters of the manipulator in this configuration are defined as follows:

{Please refer to the attachment for the table.}

Determine the rotation angle of the second degree of freedom, theta2, that must be used to bring the effector to the specified configuration.
