Practise solving trigonometric equations in degrees or radians using CAST and its period to find other solutions within the range, including multiple or compound angles and the wave function.

In this paper, we consider a Cauchy problem for a nonlinear viscoelastic equation with delay. Under suitable conditions on the initial data and the relaxation function, in the whole space, we prove a ...

The study of large-time behavior of solutions to partial differential equations is a fundamental pursuit in mathematical analysis, with profound ...

It’s surprising how much complexity and beauty emerge from these equations,” said Taiga Miyachi, referring to the winding patterns his team discovered in the vibrations of black holes. Astronomers are ...
