I want help solving differential equations

This question

my sol

syms x(t);

eqn = exp(x).*(diff(x,t)+1)==1;x(0)=1;

sol = dsolve(eqn);

problem

Error occurred during use: Indexing

Invalid indexing or function definition. Indexing is

You must follow MATLAB's indexing approach. Function argument is symbol side

Must be a number and the body of the function must be a symbol expression.

Hi @kubel

Follow the example in the dsolve() documentation

https://www.mathworks.com/help/symbolic/dsolve.html

syms x(t)
eqn  = diff(x,t) == 1/exp(x) - 1;   % rearrange the equation
cond = x(0) == 1;
xSol(t) = dsolve(eqn, cond)

xSol(t) =
