By default, int returns the general results for all values of the other symbolic parameter t.

The integral family only accepts function handles as inputs, so those functions cannot. Your dydx has singularities at isp0 and isp0 and has minima at isp7. Solve algebraic equations to get either exact analytic solutions or highprecision numeric solutions. It supports infinite intervals and can handle moderate singularities at the endpoints. Set this flag to true or 1 to indicate that fun is a function that accepts a scalar input and returns a vector, matrix, or nd array output the default value of false indicates that fun is a function that accepts a vector input and returns a vector output.

For scalarvalued problems, the function y funx must accept a vector argument, x, and return a vector result, y. The m in sqrtm distinguishes this function from sqrta, which, like a. For analytic solutions, use solve, and for numerical solutions, use vpasolve.

With the two minima being on either side of one of the singularities, you would not be able to integrate this function unless you confined yourself to the area without singularities.
