Trigonometry

The answer is 0.2867.

An obtuse angle does have a measure of over 90 degrees but it is also less than 180 degrees.

Bartholomaeus Pitiscus is best known for his book called Trigonometria which was first published in Heidelburg in 1595. It consists of work on plane and spherical trigonometry. The book had the first recorded mention of the word "trigonometry".

The supplementary angle of 57 degrees is 123 degrees

The complementary angle of 75 degrees is 15 degrees

So: 123 minus 15 = 108 degrees

phi = [(1+sqrt(5)]/2 = 1.6180, the golden ratio.

cosine(phi) = -0.0472 approx.

The value is 0.

The third quadrant.

The inverse of the inverse is the original function, so that the product of the two functions is equivalent to the identity function on the appropriate domain.

The domain of a function is the range of the inverse function.

The range of a function is the domain of the inverse function.

It is not clearly mentioned that whether it is the "THIRD" root we have to calculate.. or the "SQUARE ROOT THREE TIMES.. i.e the EIGHTth ROOT".. The answer posted here before was not correct in a sense that the if the question demands "third square root" which can also mean the "EIGHTth" root..

Re-edit:

It seems rather obvious that this answerer is new to wiki answers and is not in the habit of question interpretation. The question is most likely thus; " What is the cubic root of 0.125. The answer then would be...,

cubic root(0.125)

= 0.5

====( calculate the square root three times?!? sounds like a stretched interpretation )

Do you know what square root means? -_- if u know.. then u clearly know what "third square root means" .. huh -_-

Angular speed = 2*pi radians per 60 seconds = pi/30 radians per second.

The angle of depression is looking downwards to an object from the horizontal

The negative sine graph and the positive sine graph have opposite signs: when one is negative, the other is positive - by exactly the same amount. The sine function is said to be an odd function.

The two graphs for cosine are the same. The cosine function is said to be even.

It depends on what identity you are talking about whether its multiplicative inverse to additive inverse i mean you have to be more specific

Yes they are. Both have a a period of 2 pi

Sin(19) = 0.3256 approx.

12 * 5/6 = (12*5)/6 = 60/6 = 10

Tangent(62 degrees) = 1.88073 (rounded)

Tangent(62 radians) = -1.09751 (rounded)

Use a protractor.

YES! If you can't do algebra, you won't last ten seconds in trigonometry. It basically is algebra, just using equations within equations.

its the answer to a mathermatical problem consisting of 1 variable!

Approx 3.26 km.

Sine and cosine cannot be greater than 1 because they are the Y and X values of a point on the unit circle. Tangent, on the other hand, is sine over cosine, so its domain is (-infinity,+infinity), with an asymptote occurring every odd pi/2.

They do not. They are not animate nor sentient and so they are incapable of communicating.

with a sine wave

No. It can be used on any triangle.
