Trigonometry

quadrant one has two positive numbers.

quadrant two has neg. x numbers and positive y numbers

quadrant three has two negative numbers

quadrant fout has pos. x numbers and negative y numbers.

3.3 is only one value. you need two number to find the quadrant. 3.3 lies on the x-axis and doesnt lie in a quadrant. therefore you answer is no quadrant.

sine 810 = sine 90 = 1

hexa-decagon

a normal sine curve exists with the formula Asin(Bx+C)+D. The formula to derive a phase shift would be such: 2pi/B (for whatever value B exists at). Thus, for a normal sine curve (sin(x) we would get 2pi/1, and arrive at 2pi for the period.

In the mind. A plane is an abstract concept: it is perfectly even (flat) and infinitely long in every direction. A flat surface, such a s desktop or sheet of paper may model it, but these will only be approximations.

Hypotenuses can cave any real vale and, since real numbers are infinitely dense, the ratio of "successive" lengths is as close to 1 as you can get.

tangent of 30 degrees = 1/2 of the square root of 3 = roughly 0.5773

If you are talking about functions in 2-dimensional space, that is, functions of the sort y = f(x), then, by definition, none can be positive in the third quadrant where y is always negative.

If you are talking about functions in 3-dimensional space, ie functions of the kind z = f(x,y), then for the third quadrant in terms of x and y (x<0 and y<0), there are infinitely many functions for which z > 0.

You seem to be unaware of the fact that you could have obtained the answer much more easily and quickly by using the calculator that comes as part of your computer.

Approx 7.075 km.

180 degrees, or pi.

You can nearly:

Sine2 + Cosine2 = 1 so cos2 = 1 - sin2

so that cos = sqrt(1 - sin2)

Unfortunately, you cannot tell whether it is the principal sqrt or its negative equivalent.

Mass and weight are two different things. It does not make sense to ask which is more accurate.

Mass is used to measure an object's ability to resist a force. f = ma, or m = f/a.

Weight is used to measure an object's force applied due to gravity. Measured in newtons, f = ma, or newtons = kilograms time 9.81 meters per second squared.

i don't know :) XD

They intersect at 90 degrees

[]=theta 1. sin[]=0.5sin[] Subtract 0.5sin[] from both sides.
2. 0.5sin[]=0. Divide both sides by 0.5.
3. Sin[] =0.
[]=0 or pi (radians)

the opposite

The sine of an angle between 0 and 180 degrees is positive. The sine of an angle between 180 degrees and 360 degrees is negative. At 0, 180 and 360 degrees the sine is 0.

The sine is a periodic function with period 360 degrees, so angles differing by a multitude of 360 degrees have the same sine. Hence, for instance, the sines of the angles 0, 360, 720, ... are equal, namely 0.

In any right triangle the sine of one of the non-right angles will be positive, since these are greater than 0 and less than 90 degrees.

For all angles x (x real, x ≠ k*pi radians for integers k),

cot(x) = 1/tan(x).

circumference = 2*pi*7 = 43.98229715

arc = (120/360)*43.98229715 = 14.66076572 or 14.661 units rounded to 3 dp

This is an inequality equation in the form of:

ii < xxii/viii which is the same as 2 < 22/8
