Fourier Transform of Cosine Function Givenx(t)=cosω0tx(t)=cosω0tFrom Euler’s rule, we have,cosω0t=[ejω0t+e−jω0t2]cosω0t=[ejω0t+e−jω0t2]Then, from the definition of Fourier transform, we have,F[cosω0t]=X(ω)=∫∞−∞x(t)e−jωtdt=∫∞−∞cos...
Today We are going to learn an interesting topic which is “How to implement the Hyperbolic cosine function using Python”. You must be aware of all trigonometric functions and related terminologies as well as their corresponding angle concepts earlier. You must have solved trigonometric problems whe...

The Laplace transform is a mathematical tool which is used to convert the differential equation in time domain into the algebraic equations in the frequency domain or s-domain. Mathematically, if x(t)x(t) is a time domain function, then its Laplace transform is defined as −L...

🐛 Bug Cosine similarity function should not calculate a result over 1.0 but it does if vector size is over 84 and more. To Reproduce def cos_sim(v1,v2): return F.cosine_similarity(v1.unsqueeze(0),v2.unsqueeze(0)) vv1 = tensor(list([float(i) for i in range(84)])).unsqueeze...
In the above code, the “numpy.dot()” function takes two vectors as its arguments and retrieves the dot product. Similarly, the “norm()” function takes the input vector as an argument and receives the vector norm. It is such that Python calculates cosine similarity by dividing two vecto...
