Dear Maple user i want to extract the data from the given graph and store in excel file. where the first column contain the value of lambda in that substitude the values of delta2 ranging from 0.002 to 0.1 (atleast 20 values) and second column  contain Nb =0.1, third column Nb= 0.2 and third column Nb=0.3. Thanks in advance

restart:
h:=z->1-(delta2/2)*(1 + cos(2*(Pi/L1)*(z - d1 - L1))):
K1:=((4/h(z)^4)-(sin(alpha)/F)-h(z)^2+Nb*h(z)^4):
lambda:=Int(K1,z=0..1):
L1:=0.2: F:=10:
d1:=0.2:
alpha:=Pi/6:
plot( [seq(eval(lambda, Nb=j), j in [0.1,0.2,0.3])], delta2=0.02..0.1);
Please Wait...
