Trigonometry

you use the the 3 trigonometry functions , sin=opposite divided by hypotenuse cos=adjacent divided by hypotenuse tan=opposite divided by adjacent these are used to work out angles and side lengths in right angle triangles only!!! sine,cosine,tangent :)

acute angle = less than 90o & greater than 0o right angle = 90o obtuse angle = greater than 90o & less than 180o straight angle = 180o reflex angle = greater than 180o

1 million is 1,000,000

1 crore is 100 lakhs = 100,00,000 = 10,000,000

10 million is 1 crore

The difference between plane and spherical triangles is that plane triangles are constructed on a plane, and spherical triangles are constructed on the surface of a sphere. Let's take one example and run with it. Picture an equilateral triangle drawn on a plane. It has sides of equal length (naturally), and its interior angles are each 60 degrees (of course), and they sum to 180 degrees (like any and every other triangle). Now, let's take a sphere and construct that equilateral triangle on its surface. Picture an "equator" on a sphere, and cut that ball in half through the middle. Set the top half on a flat surface and cut it into four equal pieces. Now if you "peel up" the surface of one of those quarters and inspect that triangle, it will have three sides of equal length, and will have three right angles. Not possible on a plane, but easy as pie on the surface of a sphere. Spherical trig is the "next step up" from plane trig.

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.

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.

A feasible region is, in a constrained optimization problem, the set of solutions satisfying all equalities and/or inequalities. On the other hand a linear programming is a constrained optimization problem in which both the objective function and the constraints are linear, therefore a feasible region on a linear programming problem is the set of solutions of the a linear problem. Many algorithms had been designed to successfully attain feasibility at the same time as resolving the problem, e.g. reaching its minimum. Perhaps one of the most famous and extensively utilized is the Simplex Method who travels from one extremal point to another, which happens to be the possible extrema given the convex nature of the problem, by maintaining a fixed number of components to zero, called basic variables. Then, the algorithm arrives to a global minimum generally in polinomial time even if its worst possible case has already been proved to be exponencial, see Klee-Minty's cube.

The four quadrants.

Ancient Egyptian and Babylonian mathematicians lacked the concept of an angle measure, but they studied the ratios of the sides of similar triangles and discovered some properties of these ratios. The ancient Nubians used a similar methodology.
