I am working on inverse kinematic problem for a planar 3r robot where i needed to include the following expression.

i am not able to figure out how to incorporate +,- sign to the expression.

any help in this regard is appreciated

To be clear: MATLAB does not have a ± operator so you have to do the equivalent yourself.
