Introduction to study about polar derivative formulas:
* In calculus, differentiation is the process of finding the derivative which means measuring how a function changes with respect to its input. The derivative of y with respect to x is given by [(dy)/(dx)] .
* Polar coordinate is a two dimensional coordinate system and it is defined by x = rcos θ, y = rsin θ. To find the derivative [(dy)/(dx)] for polar coordinates, we can use the following formula.

Study about polar derivative formulas with example problem 1:
Find derivative of the function r = 8 + 5sin θ
Step 1: Given function
r = 8 + 5sin θ
Step 2: Differentiate the given function r = 8 + 5sin θ with respect to ' θ '
[(dr)/(d theta)] = 5cos θ
Step 3: Substitute all values in the polar coordinate formula
[(dy)/dx] = [((dr)/(d theta) sin theta + r cos theta)/((dr)/(d theta)cos theta - r sin theta)] .
= [((5cos theta) sin theta + (8 + 5sin theta) cos theta)/((5cos theta) cos theta - (8 + 5sin theta)sin theta)]
= [(5cos theta sin theta + 8cos theta + 5sin theta cos theta)/(5cos^2 theta - 8sin theta - 5sin^2 theta)]

To calculate the first derivative, I found the average rate of change of Emmitt Smith’s annual rushing yards from the two years surrounding the year I was deriving. Smith’s yards per year had an increasing slope in the years 1990, ’91, ’94, ’97, ’98, and 2004.

The parallax formula is derived using trigonometric functions in relation to right triangles and parallax angles. “The Six Trigonometric Functions and Reciprocals” says the six basic trigonometric functions are sine, cosecant, cosine, secant, tangent, and cotangent. In a right triangle, the sine of an angle is the opposite side from the angle divided by the hypotenuse of the triangle. Cosecant is its reciprocal. The cosine of an angle is the side adjacent to the angle divided by the hypotenuse. Secant is its reciprocal. The tangent of an angle is the side opposite of the angle divided by the side adjacent to the angle. Cotangent is its reciprocal (“The Six Trigonometric Functions and Reciprocals”).

Many years ago humans discovered that with the use of mathematical calculations many things can be calculated in the world and even the universe. Mathematics consists of many different operations. The most important that is used by mathematicians, scientists and engineers is the derivative. Derivatives can help make calculations of anything with respect to another event or thing. Derivatives are mostly common when used with respect to time. This is a very important tool in this revolutionary world. With derivatives we can calculate the rate of change of anything with respect to time. This way we can have a sort of knowledge of upcoming events, and the different behaviors events can present. For example the population growth can be estimated applying derivatives. Not only population growth, but for example when dealing with plagues there can be certain control. An other example can be with diseases, taking all this events together a conclusion can be made.
Calculus, the mathematical study of change, can be separated into two departments: differential calculus, and integral calculus. Both are concerned with infinite sequences and series to define a limit. In order to produce this study, inventors and innovators throughout history have been present and necessary. The ancient Greeks, Indians, and Enlightenment thinkers developed the basic elements of calculus by forming ideas and theories, but it was not until the late 17th century that the theories and concepts were being specified. Originally called infinitesimal calculus, meaning to create a solution for calculating objects smaller than any feasible measurement previously known through the use of symbolic manipulation of expressions. Generally accepted, Isaac Newton and Gottfried Leibniz were recognized as the two major inventors and innovators of calculus, but the controversy appeared when both wanted sole credit of the invention of calculus. This paper will display the typical reason of why Newton was the inventor of calculus and Leibniz was the innovator, while both contributed an immense amount of knowledge to the system.
Here, we can use the vectors to use the Pythagorean Theorem, a2 + b2 = c2, to find the speed and angle of the object, which was used in previous equations.
