I am trying to run the following algorithm, but it is not providing me the absolute answer as given in the link https://se​.mathworks​.com/help/​symbolic/s​olve-an-al​gebraic-eq​uation.ht

syms x

[solx, param, cond] = solve(cos(x) == -sin(x), x, 'ReturnConditions', true)

[madhan ravi]

your link doesn't go to the exact algorithm

Answer 1

[madhan ravi]

Use vpasolve() for numerical solution

syms x 
solx = vpasolve(cos(x) == -sin(x), x)

Thanks for your answer, but the problem is that I can just get one solution by using this command but I am looking for all the solutions for the given function. Check t5he following link
