[Tutor] fixed quad

[Msd De]

 I have nested integrals and need to use a fixed quad to carry out the
integration
Below is my code. Not sure of whether use of lambda function is appropriate
need help with regards to use of lambda function.
Thank you

LB=0.0
UB=etatip

         Kd01_Intg=K00_0*Fd_xp**2*f_xp*etaTerm/W
         Kdd1_Intg=F0_xp*Fd_xp*f_xp*etaTerm/W
