Hi
May I suggest that you study example 3 in "The Bending Of Beams Part 5" The beam in the example is both built in and carries two loads. However it also carries a uniform load which you will have to remove!
I am afraid that you will have to learn some Mathematics if you want to be an engineer. As a help we have some useful pages on Integration; Differential equations. Trigonometry and Coordinate (Analytical) Geometry. They all have worked examples which should help you
