How to plot the following in matlab

1)y = ce^-2x

2)I = I e^(-RT/L)

3)y = cx^(3/2)

4)y = sin2x + c/(sin^(2) 2x ) , c = 1

Answer 1

e.g

x=0:0.1:10  
y=(x.^2+sin(x))./(x+1);  % .*,  .^, ./  are operations element by element
plot(x,y)

 help plot

please tell me the procedure about all the question i am totally unaware of matlab i will be thankful to you have to submit these question
