The basic circular functions are sine, cosine and tangent. Then there are their reciprocals and inverses.

Engineers and Physicists use trigonometry, as well as people whose carrers involve acoustics, optics, and waves.

First we look at the double-angle identity of cos2x.

We know that:

cos2x = cos^2x - sin^2x

cos2x = [1-sin^2x] - sin^2x.............. (From sin^2x + cos^2x = 1, cos^2x = 1 - sin^2x)

Therefore:

cos2x = 1 - 2sin^2x

2sin^2x = 1 - cos2x

sin^2x = 1/2(1-cos2x)

sin^2x = 1/2 - cos2x/2

And intergrating, we get:

x/2 - sin2x/4 + c...................(Integral of cos2x = 1/2sin2x; and c is a constant)

2.95 = 2 and 95 hundredths = 2 95/100 which reduces to 2 19/20

The sum of the three constitutive angles of a planar triangle is always equal to 180 degrees or two right angles. And there are two things in it as well. they are diagonal and a exterior angle

The hypotenuse is the side of a right triangle opposite the right angle. The legs are the other two sides which form the right angle.

The answer depends on what information you do have.

To change a fraction into a mixed number, divide the numerator (top number) by the denominator (bottom number) to get the whole number. The remainder is the new numerator and gets written over the same denominator. Your welcome!

Commonly known as a quadrilateral, a tetragon is a polygon with 4 (four) sides.

It is an heptagon which is also a septagon because they both have 7 sides

That's a reflex angle.

0 to <90 Acute angle

90 Right angle

>90 to <180 Obtuse angle

180 Straight angle

>180 to <360 Reflex angle

360 called Full circle

a polygon with 6 sides

The fact that is has six sides makes it a hexagon but that does not explain ""convex". A convex polygon is one in which none of the angles is a reflex angle. An alternative definition of convex is that a line joining any two points inside the hexagon is wholly inside the shape.

It is not clear what numbers are represented by the alphabetic characters that appear in the sequence in the question.

The direction a ship (or really any moving object) takes is its bearing. That is maskes angles as its directions change. Using these angles and distances traveled, a ship can find how far it has moved from its original position, as well as find its current location on a map.

Trigonometry includes 12 baisic functions. Sine, Cosine, and Tangent are the three most baisic. Each of those functions has a reciprocal. Cosine's reciprocal is Secant, Sine reciprocal is Cosecant, and Tangent's reciprocal is Cotangent. Each of those six functions has an inverse funcion called Inverse Sine, Cos etc... or Arcsine, Arcosine, Arcsecant, etc.... The shorthand for each function is sin, caos, tan, sec, csc, cot. The inverses have a -1 notation like sin-1.

Technically there are only 4 parts to a memorandum. 1) The heading which consists of your distribution list, who it is from, the date and subject. 2) The body of the memo or text 3) the reference initial if you typed it, but didn't write it 4) notations - if necessary

Trigonometry is used in the design and construction of buildings, cars, planes, and many other objects. Trigonometry is used in physics and engineering whenever forces, waves, fields, and vectors are involved. Trigonometry is used in music and acoustics to design speakers, instruments, and concert halls. Trigonometry is used to coordinate launches OS space shuttles. Trigonometry is used to navigate ships and planes. Nearly every part of modern life uses trigonometry in some way.
