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 …

The height above the ground of a rider on a Ferris wheel can be modeled by the sinusoidal function h=6sin(1.05t−1.57)+8ℎ=6sin(1.05t-1.57)+8  where hℎ  is the height of the rider above the ground, in metres, and t  is the time, in minutes, after the ride starts. When the rider is at least 11.5 m above the ground, she can see the rodeo grounds. During each rotation of the Ferris wheel, the length of time that the rider can see the rodeo grounds, to the nearest tenth of a minute, is  min.
The height above the ground of a rider on a Ferris wheel can be modelled by the sinusoidal function h=4sin(3.44t+0.58)+13 where hℎ  is the height of the rider above the ground, in metres, and t is the time, in minutes, after the ride starts Based on the sinusoidal function, the maximum height of the rider above the ground, to the nearest meter, is
At noon, the tide is at mid tide of 11 feet. At 6:00 pm, the tide is at low tide of 3 feet. At 6:00 am, the tide is at its high tide of 19 feet. It takes 24 hours for the tide to complete a full cycle. Determine a sinusoidal function that models the tide height h as a function of time t(in hours). Let t = 0 correspond to noon. - High tide Mid tide Low tide d
