MATLAB: 3= 2*(e^x – e^-x)

need urgent help

How to solve this equation to find x? Thanks in advance

Best Answer

syms x
eq=3==2*(exp(x)-exp(-x));
sol=vpasolve(eq)

If you solve it with solve command, you will obtain two roots, but one of them is a complex solution. Therefore, I directly solved it with vpasolve. But also see the solution for the solve command. The result is 0.6932.

sol=solve(eq)

If you have symbolic toolbox, you can use solve() function

syms x y a b
eq = [1 1;x y;x^2 y^2;x^3 y^3]*[a;b]==[2;0;2/3;0];
sol = solve(eq);

The system have two solutions. sol is a struct. You can access the solution like this

>> sol.x
ans =
 3^(1/2)/3
-3^(1/2)/3
>> sol.y
ans =
-3^(1/2)/3
 3^(1/2)/3
>> sol.a
ans =
1
1
>> sol.b
ans =
1
1
