Sean, Thanks for the reply. I'm trying to integrate "raw data" from an experiment and there are numerous raw data inputs. The data are A1's and they are converted to C1's which I'm manipulating to integrate. luke
Given: L1 = {{x1,y1},{x2,y2},{x3,y3},{x4,y4},...........{xn,yn}}: how is L2 below, obtain: L2 = {{ax1,y1},{ax2,y2},{ax3,y3},{ax4,y4}.....{axn,yn}}
Sean, could you expand; I'm looking for a result like Nintegrate[data1] = {{x1, y1?},{x2, y2?},{x3, y3?},{x4, y4?},............{xn, yn?}} not (-x1 + x2) y1 + (-x2 + x3) y2 + (-x3 + x4) y3
Can this result be extended for "n" elements as: Given the two lists; how do you multiply them? L1 = {{X1 , y1}, {X2 , y2}, {X3 , y3}, {X4, y4},...,{Xn, yn}} L2 = {{X1 , z1}, {X2 , z2}, {X3 , z3}, {X4, z4},,},{Xn, zn}} To obtain: L1*L2...
Given an integral with a goal to plot the output as a function of one of the variable in the integrand.
Integrate[Exp[- (2 \[Pi] S Abs[x-y])/B]* Cos[(2 \[Pi] S)*(x-y)]* Sin[1 \[Pi] x]Sin[1 \[Pi] y],{x,.001,1}, {y,.001,1}] Where S and B are input numbers and x and y are variables of integration
Thanks David, I did as you suggested and the Greek symbol appeared. I used it to copy and paste where the symbol was needed and it worked great. Thanks
