steps involed in calculating this integral.
Bn= 2/L ∫ f(x) Sin(n.pi.x)/L dx.


f(X)= hX/Xo    when O<X<=Xo.

      =h(L-x)/(L-Xo) ,when  Xo<=x<L

roots of the equation..

D²x-m²x=0 . it is a differential equation

how can we write the solutions in the form of (a+ib)

Ok ihve got the previous one ...


Can u help me out in calculating the Phase Shift through a thin lens of focal length f.

where d is the  lens diameter. and h is the distance from the optical axis.

solution is like this.

P(h) = K/2f [ (d/2)² - h²].
