Relationship of trigonometric functions of real numbers?
I want to know the basic enhancement of trigonometry I am a college student, taking course of Bachelor of Science in Mathematics
If you are at college studying mathmatics at such a level your previous schooling should have taught you trigonometry. If you do not understand the relationships then you have insufficient grounding for the course on which you are on. I would suggest further study of the basics before you advance. This will save your time and that of your tutors.
How do you use periodic functions in oscillation?
Many oscillations are simple harmonic motions and such motion can be represented by a sine (or equivalently, cosine) curve.
What are the uses of trigonometry in schools?
There are few uses for trigonometry is schools just as there are few uses for languages or history or geography or, in fact, most subjects. There are three main objectives in teaching most subjects at school:
- one is to give you a taster of that subject. If you had never come across it you would never know whether or not you wanted to study it.
- a second is to provide you with enough of the basics so that, if you do choose to study a related subject at a later stage, you would not have to start from scratch. For example, if they did not teach you any mathematics, you could never be a scientist or, alternatively, your first year of studying proper science, you would have to learn basic addition!
- the third aim, is to provide you with enough basic skills to be able to perform effectively as a productive citizen in society. Despite being a mathematician, and someone who loved trig at school, for most people, this argument does not work.
You can compute sin(x) manually/numerically using Taylor's Series.
How do you make math more fun for 13 year olds?
its not exactly easy........ just give them something they like if they finish it first.
What is a iteration in geometry?
Iteration, in mathematics, is a process of solving an equation numerically. Iteration involves making an estimate for a solution to a problem. That, estimate is used as an input to make another estimate. Then that estimate as the input to get yet another estimate.
With a reasonable first estimate and an appropriate iteration procedure, the answers will converge towards the true solution. However, be aware that in some cases the process can diverge (or oscillate).
What is the rule of adding integers?
Make sure that you add units to units, tens to tens, hundreds to hundreds, and so on. Keep the digits which represent the numbers in the correct columns before you add.
What are the techniques of a good grade?
Here are some tips:
Work hard, try to understand the subject - seek help when needed. In an exam, read the questions carefully, give a complete answer showing your working, check your work.
Yes! Any multiple of 11 that is in the form of 11x10^n +209 will have an odd digit sum and will be divisible by 11. 209 is divisible by 11, and 11X10^n is too. Remember that n has to be over 1,000 for it too work.
ex. 11x10^5+209=1100209.
1100209/11=100019
How do you make a model of trignometry?
By constructing a right angle triangle which has trigonometrical properties associated with it
What are two absolute value equations that share part of a ray?
A ray, is a line that starts at one point and goes on forever. Two absolute value equations that could share part of a ray are 0,0 and 30,30.
In what ways trianlges can be classified?
Triangles can be classed as scalene, right angle, obtuse, isosceles and equilateral
Which trigonometric ratio is the best for a particular problem?
My Pre-Cal teacher taught us:
Some Old Hippie Caught Another Hippie Tripping On Acid
Sin X = Opposite / Hypotenuse
Cos X = Adjacent / Hypotenuse
Tan X = Opposite / Adjacent = SinX / Cos X
so it depends on what angle and sides are given to you.
If the period of fx equals 8 then the period of f2x is?
4. P'=P/a where Period of f(x) = P and period of f(ax) = P'
What applications require trigonometry?
carpenters use it all the time Architecture, Surveying, Astrophysics, Aerodynamics and Aviation, just to name a few.
