y=-1:0.05:15; yprim= (0.75*y)-(0.05*y.^2)-((1.5*y.^3)/(1.25+y.^3)); plot(y,yprim) hold on grid on xlabel('y'); ylabel('dy/dt'); title('plot of function(1) with b=0.05');sin(x degrees)^2*(cos(x degrees)^2+sin(x degrees)^2/(1+0.33))cos(x degrees)^2*(cos(x degrees)^2+sin(x degrees)^2/(1+0.33))
% 't' is defined in that link as,
t = linspace(0,92*pi,5000); % 5000 is arbitrarily chosen
% Minimalist version
-1/38 * sin(17/11 - 37*t) - 1/30 * sin(31/21 - 35*t)% Showing use of .* notation (not required here due to matrix dimensions)
-1/38 * sin(17/11 - 37.*t) - 1/30 * sin(31/21 - 35.*t)% Showing use of parentheses to perceptually group the terms but not
% required due to order of operations
((-1/38) * sin((17/11) - (37.*t))) - ((1/30) * sin((31/21) - (35.*t)))
