MATLAB: How to write correct matlab codes in solving equation

solve equation

I tried to used "solve" to solve the equation but got error. Here is what I have tried.

syms x solve(x+2=1,x)

Please help me correct the codes. I would like to work on harder equations and loops commands. Thanks in advance,

Anupan, use

 syms x 
 solve(x+2 == 1,x)

MATLAB: What is the correct equation

You have a variable t in your equation which is a vector. In order to multiply vectors in MATLAB you must use the syntax .*. In your case, the equation should be:

x=u*(1-exp(-s*w1*t).*(cos(w2*t)-y*sin(w2*t)));

I believe that should fix it.

MATLAB: What is the correct equation

y=5*t.*(sin(t).^2)-t.^2.*(cos(t).^2);

You should probably get in the habit of always using .* and .^ and ./ every time, until you finally encounter a situation where you need to use inner product * or matrix exponential ^ or least squared solutions to equations /
