Pytorch Codes

This is my first equation in typora $$ \begin{align*} y = y(x,t) &= A e^{i\theta} \ &= A (\cos \theta + i \sin \theta) \ &= A (\cos(kx - \omega t) + i \sin(kx - \omega t)) \ &= A\cos(kx - \omega t) + i A\sin(kx - \omega t) \ &= A\cos \Big(\frac{2\pi}{\lambda}x - \frac{2\pi v}{\lambda} t \Big) + i A\sin \Big(\frac{2\pi}{\lambda}x - \frac{2\pi v}{\lambda} t \Big) \ &= A\cos \frac{2\pi}{\lambda} (x - v t) + i A\sin \frac{2\pi}{\lambda} (x - v t) \end{align*} $$ This is the second equation $$ x = \sum x_i*3+y_i $$

This is my first code example in typora.

def hello_world(name):
    print("Hello {:}".format(name))
