Just from what you've said, you have the second derivative and you know the second derivative test, so with your second derivative, the curve is concave up when $$-\frac{3}{4}\sec^3t>0.$$ Dividing both sides by $-\frac{3}{4}$ reverses the inequality, so, dividing by 4, $$\sec^3t<0,$$ which is what the book said.Question: Find the intervals on which the graph of f is concave upward, the intervals on which the graph of f is concave downward, and the inflection points. f (x)= ln (x^2-8x+41) Find the intervals on which the graph of f is concave upward, the intervals on which the graph of f is concave downward, and the inflection points. f (x)= ln (x^2-8x+41)١٤‏/١١‏/٢٠٠٨ ... the number down or in punching it back into the calculator.

Also, find all inflection points of the function. a) Cu on l-12./2), CD on (-2,-2) and (v2,20) ip (-V2 ...Using the second derivative test: x. -2. -1. 0. 1. 2 y''. DNE. 3. 0. - 3. DNE c) concave up on (-2,0) d) concave down on (0,2).If we are trying to understand the shape of the graph of a function, knowing where it is concave up and concave down helps us to get a more accurate picture. Of particular interest are points at which the concavity changes from up to down or down to up; such points are called inflection points. Definition 5.78. Inflection Point.

Details. To visualize the idea of concavity using the first derivative, consider the tangent line at a point. Recall that the slope of the tangent line is precisely the derivative. As you move along an interval, if the slope of the line is increasing, then is increasing and so the function is concave up. Similarly, if the slope of the line is ...Below x = -2, the value of the second derivative, 30x + 60, will be negative so the curve is concave down. For higher values of x , the value of the second derivative, 30x + 60 , will be positive so the curve is concave up. We can conclude that the point (-2,79) is a point of inflection. Consider f(x) = x4. ….

Second derivative and Concavity f00(x) > 0 ⇒ f0(x) is increasing = Concave up f00(x) < 0 ⇒ f0(x) is decreasing = Concave down Concavity changes = Inflection point Example 5. Where the graph of f(x) = x3 −1 is concave up, concave down? Consider f00(x) = 2x. f00(x) < 0 for x < 0, concave down; f00(x) > 0 for x > 0, concave up.Recall that the first derivative of the curve C can be calculated by dy dx = dy/dt dx/dt. If we take the second derivative of C, then we can now calculate intervals where C is concave up or concave down. (1) d2y dx2 = d dx(dy dx) = d dt(dy dx) dx dt. Now let's look at some examples of calculating the second derivative of parametric curves.
