Given a cantilever beam of length "L". The left support "A" is fixed while the right end "B" is free. With constant EI. A counter-clockwise moment "M" is applied at "B". Using Double Integration Method, what will be the value of differentiation of deflection in y direction (y’) with respect to distance "x" from point A?
a) 0
b) 1/EI (Mx + C1)
c) -1/EI (Mx + C1)
d) 1/EI (Mx^2 + C1x + C2)
e) -1/EI (Mx^2 + C1x + C2)
