Trigonometry

Like all prisms you find the area of one of the triangular faces and then multiply by the height.

Graphic designers use math because they have to measure out models to a certain scale. They need to know how to calculate exact measurements.

The parts of a cartesian coordinate system include the origin (point 0,0), the x-axis or abscissa, the y-axis or ordinate, and the quadrants into which the x and y axes divide the plane.

In geometry, angles are studied mostly in relation to each other. In Trigonometry, angles are studied in relation to side lengths and triangles.

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.

this is a grat question wish i could help...

If it is an elliptic oval, the circumference can be calculated by πab, where a and b are the lengths of the minor and major axes.

Triangular prism

No. It is a triangular pyramid or a tetrahedron.

A triangular prism has 6 vertices and 5 faces.

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
