Dear sir I want to plot the graph for different values of F=0.1, F=0.2,F=0.5 . My codes are given and i am attaching the sample graph. For F=0.1, Nb=0.1,0.2,0.3 three curves

Similarly For F=0.2,Nb=0.1,0.2,0.3 three curves and for F=0.5, Nb=0.1,0.2,0.3 three curves. Total nine curves 

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:
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);

I want to plot contour for piecewise  function , here is my code

with(plots):
d1:=0.1:eta:=0.01:k:=2:L:=1:
mu:=0.01:delta1:=0.1:delta2:=0.2:
d1:=0.2:d2:=0.2:L1:=0.2: L2:=0.2:
h:=z->piecewise( z<=d1,    1,
                 z<=d1+L1,   1-(delta1/(2))*(1 + cos(2*(Pi/L1)*(z - d1 - L1/2))), 
                        z<=d1+L1+d2,  1 ,          
                    z<=d1+L1+d2+L2,  1-(delta2/(2))*(1 + cos(2*(Pi/L2)*(z - d1 - d2-L1-L2/2))),
                 z<=L,    1):
A1:=((k+2)*(k+3)*(1-mu)^(k+1)-2*(1-mu)^(k+2)*(k+2+mu))^(1/k):
A2:=(A1*r/h(z)^(1+3/k)):
contourplot(A2,z=0..1,r=-h(z)..h(z),colour=black,axes=boxed);

in plot line style should to like  and .so on....

line & diamond   ,   line  and circle   ,  line and cross,    line and cross,

 same should be displayed in legends

dear sir i want to plot a graph for different values of h(z) by applying do loop, hear is my codes

In K1 it should take first h(z)

In K2 it should take second h(z)

IN K3 it should take third h(z) 

restart:
h:=z->1-(delta2/2)*(1 + cos(2*(Pi/L1)*(z - d1 - L1))):
h:=z->1-(delta2/2)*(1 + cos(2*(Pi/L2)*(z - d2 - L2))):
h:=z->1+(delta2/2):

K2:=((4/h(z)^4)-(sin(alpha)/F)-h(z)^2+Nb*h(z)^4):

Dear sir,

 i want to plot a graph with  tick marks on all sides , i am attaching codes and  a sample graph, see the attachmnent,

The graph range should be displace only on x and y axis and the vaues should not be on opposite to x and y axis

please see the sample graph
