"SSA" is when we know two sides and an angle that is not the angle between the sides. use The Law of Sines first to calculate one of the other two angles; then use the three angles add to 180° to find the other angle; finally use The Law of Sines again to find the unknown sid...
In summary, the choice between using a sine or cosine wave in the equation x=Asin(wt+phi) or x=Acos(wt+phi) depends on the initial conditions of the object in motion. If the object is at x=0 when t=0, a sine wave is easiest to use, while a cosine wave...
The sine function is positive in the first and the second quadrants. The cosine function is positive in the first and fourth quadrants. In the remaining quadrants, the function returns negative values. Answer and Explanation: T...
The foundation of our civilization is tools. We didn't just evolve to a state that allowed us to use them, we began to improve them ourselves. The tools are becoming more intricate, more efficient and more perfect. It can be a hammer, an industrial robot, or a monetary relationship. Som...
We use these solutions to test some non-conventional explicit and stable numerical methods against the standard explicit and implicit methods, where in the latter case the algebraic equation system is solved by the preconditioned conjugate gradient and the GMRES solvers. After this verification, we ...
