Hi I am trying to write a code that finds approximations of sine and cosine using the equations below with a given value of theta in degrees basically as a novice programmer i am having trouble setting upa a while loop for the expansions. Also can you guys please quote …

I'm trying to implement an algoirthm descirbed here: http://pub.uni-bielefeld.de/luur/download?func=downloadFile&recordOId=2497720&fileOId=2525546 The purpose of that algorithm is to create a concept hierarchy based on a document corpus. For instants, a "Dog" concept would be a child of the "Animal" concept in such a hierarchy. To the point, I've come accross a peice …

I have the code for the first part of a problem, which is to write a program that reads an angle x (in radians) from the keyboard. Then, in a function, compute the cosine of the angle using the first five terms of this series. Print the value computed along …

I'm trying to create a program that computes the values of cos using the Taylor Series as long as the absolute value of a term is greater than 0.0001 and prints the number of terms used in the series approximation. My code is the following and as of right now …

Below are my code lines for computing cosine similarity over a list of values. My goal is to compute cosine similarity for each value in the f-list (f=[[3492.6], [13756.2], [22442.1], [22361.9], [26896.4]]) by taking a value from the list and compute how close in terms of cosine distance the rest …

Can anyone please explain to me how to compute DCT? I'm finding it hard to understand it.   I attached the formulas the Discrete Cosine Transform (DCT) and it's Inverse-DCT.

How to get the **Sine** and **Cosine** of an **inputed** number by the user?
