Hi,
I'm trying to find the zeros for this symbolic function:
2*cos(x) + x*sin(x) -2 == 0
is there a way to do it in MatLab?
Many thanks

Hi,
You can use ' solve' command to solve the equation.For more information on ' solve', please have a look at the following link: https://www.mathworks.com/help/symbolic/solve.html
You can also use ' fsolve' and ' fzero' to solve nonlinear equations.For more information please have a look at the following links:
fsolve: https://www.mathworks.com/help/optim/ug/fsolve.html
fzero: https://www.mathworks.com/help/optim/ug/fzero.html
