tipe plot

a) Tipe Plot>> x=linspace(0,2*pi,30);>> y=sin(x);>> plot(x,y)

b) Tipe Plotx=0:0.5:20;>> y=2*x.^2+5*x+2;>> z=sqrt(4*x+2);>> >> subplot(2,1,1)>> plot(x,y,'r')>> grid on;>> xlabel('Nilai x'),ylabel('Nilai y')>> legend('x thd y')>> subplot(2,1,2)>> plot(x,z,'b')>> grid on;>> xlabel('Nilai x'),ylabel('Nilai z')>> legend('x thd z')

c) Tipe stem>> x=0:0.5:20;>> y=2*x.^2+5*x+2;>> z=sqrt(4*x+2);>> >> subplot(2,1,1)>> stem(x,y,'r')>> grid on;>> xlabel('Nilai x'),ylabel('Nilai y')>> legend('x thd y')

d) Tipe Stemx=0:0.5:20;>> y=2*x.^2+5*x+2;>> z=sqrt(4*x+2);>> >> subplot(2,1,1)>> bar(x,y,'g')>> grid on;>> xlabel('Nilai x'),ylabel('Nilai z')>> legend('x thd y')>> >> subplot(2,1,2)>> bar(x,z,'m')>> grid on;>> xlabel('Nilai x'),ylabel('Nilai z')>> legend('x thd z')
