Based on that I have decided to implement those functions in my own. From the execution time point of view it seems to me that the best approach for real time application is to use the look-up table based method of calculation with improvement of precion based on linear interpolation.
Make methods @classmethod or @staticmethod scoped where possible, or just use standalone functions. You should also distinguish between the public interface of your class (methods users would call) and the internal implementation (methods only other methods call, usually indicated by a name with a leading underscore _).
Overall I think the biggest flaw is that the client needs to make their own struct with a static const long double member called value, and pass that struct to the "functions." I would have just passed the double, but C++ doesn't let you use floating-point numbers as template arguments.
3. Below is the code I wrote to perform basic Trigonometry without using the math module (except for 1 place) for the purpose of teaching myself basic trig and to improve my python. I have never taken a trig class, so please consider this fact when explaining some fallacies in my trig logic, and please help me correct it. I would like feedback on.
1) This code's task is to create graphs of various algebraic, logarithmic and trigonometric functions and relations using Python's matplotlib.plyplot module. Turning code into a graph is a process. First, I secure a list of xs using set_width(width). Then I iterate through the list by substituting each x into the function's equation.
We need to calculate the area as a function of t. Let s, m, h be the angles of second, minute and hour with respect to the trigonometric reference. Then. s = π 2 − π 30t m = π 2 − π 1800t h = π 2 − π 21600t s = π 2 − π 30 t m = π 2 − π 1800 t h = π 2 − π 21600 t. and let S, M, H be the lengths of clock's hands.
\$\begingroup\$ You picked the wrong trig identities to use. What you want are cos(q + a) = cos q cos a - sin q sin a and sin(q + a) = sin q cos a + cos q sin a. You only need to use the trig functions once in each loop, with a = 2 pi k/N. You already know sin q and cos q at the start of each loop, because q = 0.
What I am looking to do next is add in higher functions, more in-line with a scientific calculator, starting with the constants such as e and pi, then moving into trig functions. It is in handling the functions that I am having an issue with.
6. I am trying to do my c++ homework and as a part of it I have to implement a std::map with an int as its key and a value should be a specific void function, which prints some text. I can`t find an answer to what are the correct ways of doing that. This is what I have so far: void testFunc1() { std::cout << "func1\n"; } void testFunc2() { std ...
You could use function composition to define many of your functions instead of pattern matching (pattern matching isn't bad, I just prefer this style): sinAngle :: (Floating a) => Angle a -> a sinAngle = sin . angleValueRadians Also, if you made Angle an instance of Applicative, you could define addAngle like this:
