IF F=MGcos θ AND THE ANGLE BETWEEN F AND D IS θ
THEN WILL THE WORK BE MGcos^{2}θ?

MGDcos˛θ, yes. But I'm a bit concerned about your formulas to begin with. What's the setup? You might be accounting for θ once more than you need to.

I'm not sure why you assume we all have access to every textbook used for physics lectures.
