The fact that the same value is obtained when the angle in increased or decreased by any multiple of 2*pi radians (360 degrees).

The word sine, not sinx is the trigonometric function of an angle. The answer to the math question what is the four series for x sine from -pi to pi, the answer is 24.3621.

The period of a trigonometric function, since it depends on the angle of a ray centered in a unit circle, is 2 pi radians or 360 degrees.

You can invent any function, to make it periodic. Commonly used functions that are periodic include all the trigonometric functions such as sin and cos (period 2 x pi), tan (period pi). Also, when you work with complex numbers, the exponential function (period 2 x pi x i).

The six basic trigonometric functions are applicable to almost all angles. The few exceptions are tan(pi/2 + n*pi) cosec(n*pi) sec(pi/2 + n*pi) cot(n*pi) where n is an integer. This is because the functions are undefined at these values.

There can be no "closest" value. The area is pi*r^2 Using pi = 3.14 gives the area as 28.26 sq inch Using pi = 3.14159265358979 (Excel default), gives the area as 28.2743338823081 sq inches which will be closer to the true area. The value of pi has been calculated to over 10 trillion digits and each additional digit in the value of pi gives a value for the area which is closer to the true value. . And, the value of pi can be calculated to still greater accuracy which would give a closer answer.

In the domain [0, 2*pi],sin is negative for pi cos is negative pi/2 tan is negative for pi/2 Also, the same applies for all intervals obtained by adding any integer multiple of 2*pi to the bounds.

22/7 pi = 2 * integral from 0 to infinity of (1 / (t2 + 1)) dt

You can use the Insert Function button and choose the Math and Trigonometry category. From there you can pick the function you need and enter it in. All the main ones are there. You can enter in the radians using the PI function. So to get the SINE for 45&Acirc;&deg; you would enter it as follows: =SIN(45*PI()/180) You can also use the RADIANS function: =SIN(RADIANS(45))

The function sec(x) is the secant function. It is related to the other functions by the expression 1/cos(x). It is not the inverse cosine or arccosine, it is one over the cosine function. Ex. cos(pi/4)= sqrt(2)/2 therefore secant is sec(pi/4)= 1/sqrt(2)/2 or 2/sqrt(2).

The range of the arcsinx function is restricted because it is the inverse of a function that is not one-to-one, a characteristic usually required for a function to have an inverse. The reason for this exception in the case of the trigonometric functions is that if you take only a piece of the function, one that repeats through the period and is able to represent the function, then an inverse is obtainable. Only a section that is one-to-one is taken and then inverted. Because of this restriction, the range of the function is limited.

Trigonometric functions are periodic so they are many-to-one. It is therefore important to define the domains and ranges of their inverses in such a way the the inverse function is not one-to-many. Thus the range for arcsin is [-pi/2, pi/2], arccos is [0, pi] and arctan is (-pi/2, pi/2). However, these functions can be used, along with the periodicities to establish relations which extend solutions beyond the above ranges.

y = sin x is such a function. It has an inverse, of course; but the inverse, sin-1, strictly speaking, is not a function.Example: Given that x = pi/6, y must equal 0.5. However, given that y = 0.5, x can equal pi/6, 5 pi/6, 13 pi/6, 17 pi/6, or an infinity of values, both positive and negative.For y to be a function of x, and x to be, also, a function of y, there must be exactly one value of y that answers to a given value of x, and vice-versa. Then, and only then, is each function the inverse of the other.

The value of Pi is 3.14 so the value of Pi by 2 is 6.28.

That's pi, the numerical value of the ratio of the circumference of a circle to its diameter.

Look on a unit circle graph and see what kind of pi it has. For example 90 degrees is pi/2

The value of pi (&Iuml;&euro;) is3.1415926535897932384626433832795028841971693993751.........

The approximate value of pi is 3.14159265.

You get the value of pi by dividing the circumference with the diameter of a circle. pi = c/d

The value for Pi for math is 3.14. Pi is the 16th letter in the Greek alphabet.

No one has fully discovered pi. Pi is believed to be irrational.

Multiply the angle by 2, and square the magnitude. The angle can be rewritten between (-180&Acirc;&deg; &amp; +180&Acirc;&deg;) (or -pi and +pi radians), after multiplying.

the value of pie is ALWAYS 3.14 The deliciousness of pie gives it it's value. In mathematical terms, pi is the ratio of the circumference to the diameter of a circle.
