Minimization

In mathematics, traditional optimization problems are typically expressed in terms of minimization. When we talk about minimizing or maximizing a function, we refer to the maximum and minimum possible values of that function. This can be expressed in ter…

Maxima and Minima

The extreme points of a function are the maximum and the minimum points of the function. A maximum is attained when the function takes the maximum value and a minimum is attained when the function takes the minimum value.

Derivatives

A derivative means a change. Geometrically it can be represented as a line with some steepness. Imagine climbing a mountain which is very steep and 500 meters high. Is it easier to climb? Definitely not! Suppose walking on the road for 500 meters. Which …

Concavity

In calculus, concavity is a descriptor of mathematics that tells about the shape of the graph. It is the parameter that helps to estimate the maximum and minimum value of any of the functions and the concave nature using the graphical method. We use the …

According to one model that attempts to account for air resistance, the distance s(t)(in meters) traveled by a falling raindrop satisfies d2s/dt2=g−0.004/D(ds/dt)^2 where DD is the raindrop diameter and g=9.8 m/s^2. Terminal velocity vtermvterm is defined as the velocity at which the drop has zero acceleration (one can show that velocity approaches vtermvterm as time proceeds). Find vterm in terms of g and D. Find vterm for drops of diameter 10^−3 m.

In the given question , consider a particle moving along the x-axis, where x (t) is the position of the particle at time t, x'(t) is its velocity, and x"(t) is its acceleration? x(t) = t3 - 6t2 + 9t - 2, 0 ≤ t ≤ 5

Researchers in Alaska have developed models that can be used to estimate the mass of a polar bear. For bears that are caught in the spring of the year M(x, y) = 0.000199x1.2823y1.4874, where M(x, y) is the mass of the bear (in kg), x is the straight-line body length (in cm), measured from the tip of the nose to the base of the tail, and y is the girth (in cm), measured directly behind the shoulders.
