Concave interval calculator.

A graph is concave up where its second derivative is positive and concave down where its second derivative is negative. Thus, the concavity changes where the second derivative is zero or undefined. Such a point is called a point of inflection. The procedure for finding a point of inflection is similar to the one for finding local extreme values ...Example from p. 320, #3.In Mathematics, the inflection point or the point of inflection is defined as a point on the curve at which the concavity of the function changes (i.e.) sign of ...Free second order differential equations calculator - solve ordinary second order differential equations step-by-step

To find these intervals, first find the critical values, or the points at which the first derivative of the function is equal to zero. Split into separate intervals around the values that make the derivative or undefined. Step 5 Substitute a value from the interval into the derivative to determine if the function is increasing or decreasing.
