Trigonometry

It's hard to say. The concept is very old. I would start with the related link article on Wikipedia.

1 rpm means 1 revolution per minute. A yard is distance. The revolution can be translated into a distance by knowing the time of revolution and the radius of the circle of revolution.

If you wish to communicate information to your audience then the answer is 47-gon.

If you want to (a) appear pompous or pretentious, (b) not communicate but obfuscate and (c) irritate your audience, you could try tetracontaheptagon.

It is 54.2 degrees.

A triangular prism meets those criteria.

Well I don't exactly get "the solution", but simplifying the equation is quite simple. Maybe that's what you're looking for. Here are the steps for simplifying it.

costancsc = 1

1. Change tan to sin/cos

2. Change csc to 1/sin

cos(sin/cos)(1/sin) = 1

And as you can now see, the first cos cancels with the second one under the sin/cos fraction, and the first sin cancels with the second one under the 1/sin fraction consequentially leaving you with 1 = 1.

For a better look, notice this fraction when all three parts are combined

cos * sin * 1

----------------

cos * sin

See how the cos and sin cancel each other leaving you with 1 * 1 * 1 which is just 1. Therefore the final simplification is just 1 = 1.

I hope this helps!

The disadvantage of trigonometry is that it requires an intellectual effort to learn it. It is much easier to eat pizza, than it is to learn trigonometry. Put down that textbook and order a pizza. Yum!

Cosine(38) = Cos(38) = 0.788010753 ( per calculator) or 0.7880 (per Castle's Four Figure Tables).

The explicit formula for a sequence is a formula that allows you to find the nth term of the sequence directly without having to find all the preceding terms. To find the explicit formula for a sequence, you need to identify the pattern or rule that governs the sequence. This can involve looking at the differences between consecutive terms, the ratios of consecutive terms, or any other mathematical relationship that exists within the sequence. Once you have identified the pattern, you can use it to create a formula that will generate any term in the sequence based on its position (n) in the sequence.

Well, honey, a trapezium can have 0, 1, or 2 obtuse angles. It all depends on the specific shape of the trapezium. So, you might want to whip out that protractor and start measuring those angles if you're curious.

Yes. Getting a tan depends only on exposure to the sun, not the temperature of the air. In fact, colder temperatures may make getting a tan easier, since the lower atmospheric pressure means that there are fewer particles in the air to block UV radiation.

Well, darling, if tangent k equals 0.575, then angle k is approximately 29.74 degrees. Just remember to use your trusty calculator and make sure it's in the correct mode before you go crunching those numbers. Happy calculating, honey!

The doman can extend from negative infinioty to positive infinity. Its range is from (+)1 to (-)1.

Cosine (0) = 1

Sin(0) = 0

The sine and cosine curves are two intertwining curves, that complement each other, hence the words 'Sine (Curve) and Cosine ( COmplementary Curve).

by using models, duh

(sqrt 2) / 2

To find which angle has a sine of 0.13, you calculate

arcsin or sin^-1(0.13) =7.47 degrees

7.47 degrees has a sine of 0.13.

There is also another angle , below 360 , has a sine of 0.13. Subtract 7.47 from 180.

180-7.47 = 172.53 degrees also has a sine of 0.13.

It is sin(42°)
