The length s of a shadow cast by vertical gnomon of h height h when the angle of the sun above the horizon is theta can be modeled by the equation. s=hsin(90degrees-theta)/sin(theta) , 0 degrees < theta< 90 degrees A) verify the expression for s is equal to h cot theta B) Use a graphing utility to complete the lengths s for different values of theta. Let h=4ft. (round to two decimal places) theta theta s 15 degrees 30 degrees 45 degrees 60 degrees 75 degrees 90 degrees C) use your table from part B to determine the angle of the sun that results in the length of the shadow D) what time of the day is it when the angle of the sun is above the horizon is 90 degrees.
Optimization
Optimization comes from the same root as "optimal". "Optimal" means the highest. When you do the optimization process, that is when you are "making it best" to maximize everything and to achieve optimal results, a set of parameters is the base for the selection of the best element for a given system.
Integration
Integration means to sum the things. In mathematics, it is the branch of Calculus which is used to find the area under the curve. The operation subtraction is the inverse of addition, division is the inverse of multiplication. In the same way, integration and differentiation are inverse operators. Differential equations give a relation between a function and its derivative.
Application of Integration
In mathematics, the process of integration is used to compute complex area related problems. With the application of integration, solving area related problems, whether they are a curve, or a curve between lines, can be done easily.
Volume
In mathematics, we describe the term volume as a quantity that can express the total space that an object occupies at any point in time. Usually, volumes can only be calculated for 3-dimensional objects. By 3-dimensional or 3D objects, we mean objects that have length, breadth, and height (or depth).
Area
Area refers to the amount of space a figure encloses and the number of square units that cover a shape. It is two-dimensional and is measured in square units.
The length s of a shadow cast by vertical gnomon of h height h when the
s=hsin(90degrees-theta)/sin(theta) , 0 degrees < theta< 90 degrees
A) verify the expression for s is equal to h cot theta
B) Use a graphing utility to complete the lengths s for different values of theta. Let h=4ft. (round to two decimal places)
theta
| theta | s |
| 15 degrees | |
| 30 degrees | |
| 45 degrees | |
| 60 degrees | |
| 75 degrees | |
| 90 degrees | |
C) use your table from part B to determine the angle of the sun that results in the length of the shadow
D) what time of the day is it when the angle of the sun is above the horizon is 90 degrees.
