x= [ 0:pi/18:pi/2];A=11;B=12;C=9;D=8;K1=12;K2=18;syms VE = A.*sin(x)+B.*cos(x);F = C.*sin(x)+D.*cos(x);Z = [ E-V K1; K2 F-V];DT=det(Z); %%%%%determint of Matrix Z which comes a polynomial of order 2 in V
cx = coeffs(DT,V);S0 = collect(simplify(cx(:,3)),k) %%%%%coefficient of V.^2
S1 = collect(simplify(cx(:,2)),k) %%%%%coefficient of V
S2 = collect(simplify(cx(:,1)),k) %%%%constant term
v1 = zeros(1,length(x));for ii = 1:numel(x) V1 = roots([S0(ii),-S1(ii),S2(ii)]); v1(ii) = sqrt((V1(1,1))./p); end
Firstly,I want to calculate determint of matrix Z which comes a polynomial of degree 2 in V for all value of x. Then I want to find two values of V from that polynomial….Plz Help
