I am trying to use the function "solve" to find out the solution of inequality specified in cond1. Cond1 is shown in the following picture:
However, the solution is not obtained. I also plot the function given by the left of "cond1". Corresponding result shows there exactly exists the feasible solution.
Help!
Thank you in advance!
syms x;cond1 = (x - 7) * x^2 / 2 - (4 + x)*2 >= 0;sol = solve(cond1, x, 'ReturnConditions', true);sol.conditions
