What is the memory devise to remember the order of the trigonometric ratios?
One that is popular in the UK is
SOH - CAH - TOA
Sine = Opposite/Hypotenuse and so on.
You are meant to remember it as rhyming with "soccer tour". I don't find the latter part particularly convincing, though.
Is 2 cot x sin x cos x equals 2 2 sin 2 x an identity?
No.
But that could be because of limitations of the browser used by Answers.com. This means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals".
What is the square root of negative 2 the square root of 3 squared plus negative 2 squared?
sq rt (-2) + (sq rt 3))2 + (-2)2
= i(sq rt 2) + 7 = 7 + i(sq rt 2) answer
this is a complex number, it cannot be further simplified.
Were does the word injustice come from?
In is an English prefix meaning "not". The word Justice comes from the Roman empiror Justinian who created a code of laws which systemized a legal system and created universal punishments for certain crimes.

What are the attributes of a cosine function?
There are many "attributes" of a cosine function. Some examples of attributes are as follows:
For, constants a, b, n,
y=a*cos(nx)+b has an amplitude of a, a period of 2pi/n, a range of [-a+b,a+b], a derivative of y'=-an*sin(nx).
Using Pythagoras' theorem it is 20 feet
How do you find the perimeter of a triangle when two angles are given And one is a 90 degree angle?
Knowing only the angles of a triangle does not provide enough information to determine its perimeter. You must know the length of at least one side.
Somehow I messed up andused 31 instead of 35

Do a Google search for Diagonal of a cube
Find this website.
mathcentral.uregina.ca/QQ/database/QQ.09.04/brett1.HTML - Draw a cube
You will see how to find the diagonal of a cube.
You use Pythagorean Theorem
Draw a cube
Label each side as s
Draw the diagonal of the base of the cube
Diagonal of base = (s^2 + s^2 )^0.5
Let the diagonal of the base be the horizontal side of the right triangle whose hypotenuse is the diagonal of the cube.
The height of the cube is the vertical side of the right triangle whose hypotenuse is the diagonal of the cube.
Now determine the length of the diagonal of the cube.
(diagonal of base)^2 + (height of cube)^2 = (diagonal of cube )^2
Diagonal of base = (s^2 + s^2 )^0.5….Height of cube = s
Use Pythagorean Theorem
(diagonal of cube )^2 = (diagonal of base)^2 + (height of cube)^2
(diagonal of base)^2 = [(s^2 + s^2 )^0.5]^2 = s^2 + s^2
height of cube)^2 = s^2
(diagonal of cube)^2 = (s^2 + s^2 + s^2)
(diagonal of cube )^2 = (3 * s^2)
diagonal of cube = (3 * s^2)^0.5 = 35
(3 * s^2)^0.5 = 35
Square both sides
3s^2 = 31^2 = 1225
s^2 = 408.33
s = 40833^0.5
s = 20.2 cm
How many vertices or corners in a cube?
Cube means a 3 dimensional figure. Its faces are in square shape. Cube has 6 square faces, attached by one edge of a square with another edge of another square . Two types of cubes are there one is solid cube and other is hollow cube. If three square faces come in contact with one another by their edges then we get a corner or vertex. So, the number of corners or vertices are 8.
A cube has 8 vertices, 12 edges and 6 faces
How do you convert meters per second squared to feet per second squared?
To convert meters to feet, multiply by 3.281. It does not matter about the "per second squared" since that is present in both sides.
Why did that he was the father of algebra?
If you really want to get an answer, ask a better question. I can't even tell what you are asking.
Using trigonometry its perimeter rounds up to 14 cm and its area rounds up to 8 square cm
What is first trigonometry or calculus?
Trigonometry came first thousands of years ago. Calculus was only discovered several hundered years ago.
Tangent is a function that can have any real value. Therefore one tangent can take any value in (-∞, ∞).
Find two polynomials whose ratio simplifies to 3x-12x plus 1 and whose sum is 5xsquared plus 20?
The question cannot be answered because the ratio of the polynomials cannot simplify to "3x-12x plus 1" since that is not a simplified form: it simplifies to -9x + 1.
Solve 5x-3is less than 3x plus 1 when x is an integer?
5x-3 < 3x+1 5x-3x < 1+3 2x < 4 Divide both sides of the inequality by 2 to find the value of x: x < 2 So x is an integer whose value is less than 2 such as 1, 0, -1, -2, -3, .........
