SymPy is entirely written in Python. This function is easily defined as the ratio of the hyperbolic sine and cosine functions (or expanded, as the ratio of the halfsum and halfdifference of two exponential . The main reason cotdg is in scipy.special but not cot is that the underlying special functions library that we use for the degree versions implements cotdg as well as sindg, cosdg, and tandg because it can implement cotdg with the same code as tandg . ''' Numerically solves the equation l = -cot l. Produces a plot of l versus -cot l and produces a text file of n zeroes of f (l) = l + cot l. necula@google.com, October 2019.. JAX implements certain transformations of Python functions, e.g., jit, grad, vmap, or pmap.The Python functions to be transformed must be JAX-traceable, which means that as the Python function executes the only operations it applies to the data are either inspections of data attributes such as shape or type, or special operations .
