syms x a
series(x)=sym(zeros(1));
Y=sym(zeros(1));
m=sym(1);
Y(1)=0;
Y(2)=a;
%N=input ('enter the number of coefficient required')
for k=1:6
Y(k+2)=((18*kroneckerDelta(k,m)-9*Y(k)))/(k*(k+1));
end
disp(Y)
for k=1:6
series(x)=series(x)+Y(k)*(power(x,k-1));
end
series
M=series(pi/2)-1
a=fsolve(M,0)
The last line is showing error and further i just want to evaluate the series by putting value of a by using command .But again getting error

Thanks
now i use the command to substitute the value in the series but i not displaying correct answer
series
syms x a
series(x)=sym(zeros(1));
Y=sym(zeros(1));
m=sym(1);
Y(1)=0;
Y(2)=a;
%N=input ('enter the number of coefficient required')
for k=1:6
Y(k+2)=((18*kroneckerDelta(k,m)-9*Y(k)))/(k*(k+1));
end
disp(Y)
for k=1:6
series(x)=series(x)+Y(k)*(power(x,k-1));
end
series
M=series(pi/2)-1
a=solve(M)
series
