Question

Please make a matlab program for these questions

lark and symbol is meaning full in a source code. So use them carefully hything other than your roll number and signature on this question paper Q1 Write MATLAB command to plot 4sincx) and 3cos(v) together, for -3nx2.m. Q.2 Decay of radioactive materials can be modeled by the equation A-Aoe where A is the amount at time t, Ao ls the amount at t = 0, and k is the decay constant (ks 0). lodine-132 is a radioisotope that is used in thyroid function tests. Its half-life time is 13.3 hours. Calculate the relative amount of lodine 132 (A/Ao) in a patient's body 48 hours after receiving a dose. After deter- mining the value of k, define a vector0,4,8,. , 48 and calculate the cor- responding values of A/Ao

Answer 1

Plotting.m:

x = -3*pi:0.1:2*pi;
f = 4*sin(x);
g = 3*cos(x);
plot(x,f,x,g)
grid on

Output:

octave:25> source("Plotting.m") .2 .3 -4 10 -5 10
