How can the unit circle be used to apply trigonometric functions to all real numbers?

The basic idea is that a complete turn around the unit circle has a length of 2 x pi (i.e., approximately 6.28). For numbers larger than 2 x pi, you go that distance around the unit circle, moving around it more than once - and eventually end up on some point on the unit circle. For example, if you go a distance of 3 x pi around the unit circle, that is equivalent of a distance of pi (equal to 180 degrees).
For negative numbers, you simply move around the unit circle in the opposite direction.

What is the difference between a line graph and a linear equation?
A linear equation, when plotted, must be a straight line. Such a restriction does not apply to a line graph.y = ax2 + bx +c, where a is non-zero gives a line graph in the shape of a parabola. It is a quadratic graph, not linear. Similarly, there are line graphs for other polynomials, power or exponential functions, logarithmic or trigonometric functions, or any combination of them.
When are two functions inverse of eacother?
Two functions are the inverse of one another if, for any value "x" (within the relevant range of numbers), if you apply the first function, and then you apply the other function to the result, you get the original value ("x") back. For example, starting with 3, if you square it you get 9; if you take the square root of 9, you get 3. The same happens for any non-negative number; thus, squaring and taking the square root are inverses of one another.
When is area bigger than perimeter?
It depends on the shape. Different conditions will apply for a circle, a polygon with n sides.
If 0 and 1 are not composite or prime numbers then what are they?
First, zero is not applied to the terms prime and composite because the definitions only apply to natural numbers (positive whole numbers, which does not include zero). One is not prime or composite because one is the unit that is used within the definition of prime of composite numbers, and many definitions of prime and composite even exclude one from the definition. If you want to categorize one within a discussion of prime and composite, it is common to simply call one the unit.
What is the radius of a 250 sq ft circle?
250 sq.ft. is the area of the circle. Apply the Area eq'n A = pi r^2 Algebraically rearrange r^2 = A/ pi r = sqrt(A/pi) Substituting r = sqrt( 250/3.141592....) r = sqrt(79.57747165...) r = 8.920620581.... ft. r = 8 ft 11.047... inches. ~ 9ft
What algebra 2 problem equals 24?
What topics are included in "Algebra 2" may vary depending on the specific textbook. But in general, if you want an equation that has a certain solution, in this case 24, you can start with the equation:x = 24 Then you can do several operation on this equation, always doing the same on both sides, such as: * Add or subtract the same number on both sides * Multiply or divide both sides by the same number * Square both sides * Apply functions, such as trigonometric functions, inverses trigonometric functions, exponential functions, etc. In general, you can do this repeatedly.
What Three challenging math equations that equal to a 100?
Start with the equation:x = 100 Then, do different transformations, doing the same thing to both sides of the equation - you might add the same number to both sides, then multiply by some number, then add again; or at some point you might square both sides, or apply exponential, logarithmic, trigonometric, and inverse trigonometric functions. You can make it as challenging as you want, this way.
What are the functions of an acute angle of a right triangle?
Any function whose domain is between 0 and 90 (degrees) or between 0 and pi/2 (radians). For example, the positive square root, or 3 times the fourth power are possible functions. Then there are six basic trigonometric functions: sine, cosine, tangents, cosecant, secant and cotangent, and the hyperbolic functions: sinh, cosh, tanh etc. These, too, are not specific to acute angles of a right triangle but apply to any number.

How do you apply trigonometry in other fields?
There are an enormous number of uses of trigonometry and trigonometric functions. For instance, the technique of triangulation is used in astronomy to measure the distance to nearby stars, in geography to measure distances between landmarks, and in satellite navigation systems. Wikipedia has a page on the uses of trigonometry. Click on 'related links' below to go to that page.

How do you calculate derivatives in math?
Usually you memorize a number of rules, or look them up in tables - for example, rules for the derivative of powers, trigonometric functions, addition, multiplication, etc. - and apply them to specific cases. This includes applying the "chain rule", for more complicated expressions. For a quick overview, read the Wikipedia article on "Derivative". For more details, read an introductory book on Calculus.
How do you apply sets to numbers and functions?
A set is a collection of distinct objects. Each objectin a set is called an element or member of the set. You can use set notation to write a set by enclosing the elements of the sets in braces. For example, if A is the set of whole numbers less than 6, then A = {0,1,2,3,4,5}.
What formula is apply to find area of semi circle?
If the radius of the circle is R, then the area of the whole circle is πR2 So the area of the semicircle is 0.5*πR2
What is the Alegbraic Rule?
There is no one rule to algebra. There are different rules that apply to different functions.
