Trigonometry

in trigonometry

From Greek.Trigon comes from 3-sided figure, now known as a triangle.

Metry comes from measurement.

That depends on the surface and the units, but the surface area tells us that infomation.

First, they contact Darth Vador. When he arrives, they locate the secret banana together and attach a string to it. They throw it into the ocean, and use trigonometry to locate dolphins. Then the fly off into space, and defeat Luke Skywalker.

The basic functions are sine, cosine, tangent, cosecant, secant and cotangent. In addition, there are their inverses, whose full names use the prefix "arc" [arcsine, arc cosine, etc] but are more often written as sin-1, cos-1 and so on.

the person who did this was ben Franklin

I am trying to find the answers to this....and no the answer is not ben Franklin...sorry

I agree it is not ben Franklin...good try though

They are classified as: scalene, obtuse, right angle. equilateral and isosceles

They mean that the expression to the left of the sign is greater than or less than (as appropriate) the expression to the right of the sign.

Assume the angle u takes place in Quadrant IV.

Let u = arctan(-12). Then, tan(u) = -12.

By the Pythagorean identity, we obtain:

sec(u) = √(1 + tan²(u))

= √(1 + (-12)²)

= √145

Since secant is the inverse of cosine, we have:

cos(u) = 1/√145

Therefore:

sin(u) = -√(1 - cos²(u))

= -√(1 - 1/145)

= -12/√145

Otherwise, if the angle takes place in Quadrant II, then sin(u) = 12/√145

That depends on your profession. If you are a math teacher, then you might use a lot of Trig. If you are an engineer, working with forces on any object from different directions, then you would use trig. Electrical engineers use trig. Surveyors use trig.

Trigonometry is essential to the study of higher mathematics (calculus) and to the understanding of many scientific and engineering principles. Trigonometry and calculus can be used to model many shapes, motions, and functions in daily life.

A part of a circle's circumference is an arc

One radian is about 57.3 degrees

Assuming that neither of the given sides is the hypotenuse, then if A is one of the acute angles, tan(A) = 19/63

So A = arctan(19/63) = 16.8 degrees. The other acute angle is 73.2 deg.

The hypotenuse is a side, not an angle. However, if you mean the angle across from the hypotenuse, it is always 90 degrees, or pi/2 radians because hypotenuses only exist in right triangles.

Quadrant I.

'Theta' is the eighth character in the Greek alphabet. It is not often used as a mathematical constant (such as 'Pi'), but rather as a variable. It is commonly, but not always, used to represent some arbitrary angle.

Every triangle have 6 main parts: 3 sides and 3 angles. On a right triangle one of the angles has to be a right angle, meaning it has a 90 degree angle.

You cannot "solve" ungrouped data since ungrouped data is not a question. You can calculate the mean or the variance, standard deviation or skewness, or a whole range of other measures for ungrouped data. But you have not specified what.

sin(0) = 0, sin(90) = 1, sin(180) = 0, sin (270) = -1

cos(0) = 1, cos(90) = 0, cos(180) = -1, cos (270) = 0

tan(0) = 0, tan (180) = 0.

cosec(90) = 1, cosec(270) = -1

sec(0) = 1, sec(180) = -1

cot(90)= 0, cot(270) = 0

The rest of them:

tan(90), tan (270)

cosec(0), cosec(180)

sec(90), sec(270)

cot(0), cot(180)

are not defined since they entail division by zero.
