What are some facts about hexagons?

A hexagon can be both regular and irregular. A regular hexagon occurs when all of the angles are equal on all six sides of the hexagon. This creates the typical hexagon shape with six tiny corners all in exact proportion to one another. This shape can be seen in the honeycomb of bees. Each cell in a honeycomb is a perfect regular hexagon. The reason for this is that a hexagonal structure can create the most compact honeycomb. An irregular hexagon can be made in a number of different ways as long as the shape has six straight sides.A hexagon can also be both concave or convex. A concave hexagon..

What is the importance of mathematics in mechanical engineering?

A person who works in the mechanical engineering field will also need to be able to work successfully on a team as well as with a focused and disciplined vision. Mechanical engineers are able to work with focuses in mathematics, physics, chemistry or electrical engineering. From there, mechanical engineers can focus on specialty areas, such as mechanics, design, business studies, information technology, thermodynamics, materials science and production technology, marine technology, paper technology, environmental engineering, industrial science, lightweight construction, textile engineering an..

What is a normative question?

Normative questions are often used to promote normative arguments in public forums or political debates. A normative argument is an argument presented for the sake of bringing about a specific change, action or social outcome. The answers obtained through positive questions, such as those that can be answered by "yes," "no" or a specific amount, are often used to support the normative argument for change. Positive questions provide a basis of comparison consisting of "what is" to the "what should be" that is determined by the response to the relevant normative question.

What is the derivative of sin squared?

The derivative of sine squared can be determined by using the chain rule. Under the chain rule, the equation becomes two times the sine of x times the derivative of the sine of x. The derivative of the sine of x is the cosine of x, resulting in the formula 2sin(x)cos(x). The formula 2sin(x)cos(x) can be simplified down to the sine of two times x, expressed as sin(2x).

What is the equation to convert degrees to radians?

A simple example using this equation is to convert 60 degrees into radians. By substituting 60 degrees into the equation, one finds that radians = (60 x pi)/180 = pi/3 = 3.142/3 = 1.047 radians.Students can manipulate the equation rad = (deg x pi)/180 such that they multiply both sides of the equation by 180 degree and divide by pi to get the new equation (rad x 180)/pi = deg. This is the equation to convert from radians to degrees. As a check that this equation is correct, students can use the result of 1.047 radians in this equation, which should give the answer 60 degrees.A circle has 360 d..

What is cos 0 degrees equal to?

The cosine of an angle can be found by calculating the ratio, or by calculating the value using the cosine function on a scientific or graphing calculator. The cosine is related to the trigonometric functions sine and tangent. The cosine function can be used to evaluate angles expressed in either degrees or radians. The inverse of the cosine function is known as arccos.

What is an integer?

Numbers are divided and classified by types. Like integers, natural and whole numbers are also types of numbers. Natural numbers, sometimes called counting numbers, are used for counting and ordering objects. They are the first numbers children learn in school. They begin with one and span as far as a person can count. Whole numbers include all natural numbers in addition to zero and, like the natural category, are always positive.

What is the significance of ln 1/x in calculus?

The derivative of a function is used to find the slope of the tangent at a given value of "x." Finding the derivative of both sides in respect to "x" gives the equation e^y dy/dx = 1, as the derivative of "x" is 1. Because e^y is equal to "x," then x dy/dx = 1, and dividing both sides of the equation by "x" gives the proof that d/dx of ln(x) = 1/x.

What is the derivative of 2sin(x)?

The proofs for the trigonometric derivatives are fairly long, so it is easier to simply memorize the derivatives for the six basic trigonometric functions. The derivative of sin(x) is cos(x). The constant multiple rule states that the value of the derivative of a function multiplied by a constant is the derivative of the original function multiplied by the constant. To find the derivative of 2sin(x), the 2 is multiplied by the cos(x) to give 2cos(x).
