hello
i have seen video and read it
for solving factorial which mosfet circuit is used

what is in hourofcode.com, please tell

hourofcode.com promotes a short 1-hour training on how to start with computer programming, with different exercises for school children, from ages 4 to 18.
This website uses a lot of computer graphics to provide an intuitive understanding of programming.

If you want a more text-based introduction to a programming language that you could use to calculate sin(x) and cos(x), you could try this website:
https://www.learnpython.org/

There are many kinds of sequential programming languages that could be used to calculate sin(x) and cos(x) - this same site has tutorials on C, C++, Java, Perl and others.
For a survey, see: https://en.wikipedia.org/wiki/Programming_language

There are also some radically different types of programming systems like Artificial Neural Networks, which train themselves (to some extent). These are loosely based on operation of the human brain. These are generally not so useful for calculating sin(x) and cos(x), but they have proven very valuable for high-speed parallel processing images and speech, and playing games. These perform best on specialised, highly parallel processors.

which processor are used in bank?

There are many banks, and every bank uses many different processors, for many different purposes.
No bank will give you a list (even if one person knew them all), as banks are concerned that people will try to hack the bank and steal their money, or their customer details.
I think that this concern is well-justified.

hello
then how the mosfet calculate the calculation in computer processor how logic circuit is design in it i have seen adder circuit with and or gates does they do the function

[evan_au]

logic circuit is design in it i have seen adder circuit with and or gates does they do the function

A mathematician named George Boole worked out how to create logic with statements that are TRUE or FALSE.
Almost any logical statement can be represented by using a combination of AND, OR and NOT statements.
See: https://en.wikipedia.org/wiki/Boolean_algebra

Much later, Claude Shannon discovered that this logic could be implemented by electrical circuits, which could process any type of information at high speeds. Today, we often use MOSFETS to do these logical functions.
By linking these logic "gates" together we can perform more complex functions like addition, subtraction, multiplication, string-matching, graphic processing and sin(x) and cos(x).

These "hardware" functions are very powerful at performing a single task, but they are expensive to build. They take many MOSFETS to perform a function which a particular computer may never be required to perform. "Hardware" implies "not flexible".

So most computers have a general-purpose processor core which can do all of these things - not as fast as a hardware implementation, but they can do it very flexibly. And if a better method is discovered next week, new software can be downloaded, and all of the computers will now perform better. "Software" implies "flexible".

So, for most people, if you want to know how to perform some function on a computer, it is easiest to work out how to do it in software. This does not require you to design at the level of MOSFETS.

There are some technologies called Field-Programmable Logic Arrays that have some of the benefits of both hardware and software. They offer some of the speed benefits of hardware, but some of the flexibility of software. This design requires both hardware and software skills.

Hello
How to build Logic circuit that can find cos angle and sin angle values at high speed like processor build fromMosfet or transistor

[Bored chemist]

You keep asking questions with answers so long they would take a book.

How to build a Logic circuit that can find cos angle and sin angle values at high speed like processor build from Mosfet or transistor

For hardware implementation, if you want more accuracy than a lookup table, sine and cosine often use the CORDIC algorithm, rather than Taylor Series.
The CORDIC algorithm is available as a standard building block from chip manufacturers.
But you still need to know the same basic information as for the lookup table: What is the input range of x, how many input bits, how many output bits?

For example, see:
https://www.xilinx.com/support/documentation/ip_documentation/cordic/v6_0/pg105-cordic.pdf

Remember, this is one small component of an overall computer system!
