In the last example, the notation−|2|means to take the absolute vale of 2 (which is 2) and then apply a negative to it (i.e. multiply by -1). Thus, it is equal to -2. View Video Only Save Timeline Video Quiz Course
The function for this model would bey=2.75x. The domain is the amount of gasoline that could be put into the tank, so in interval notation, the domain would be[0,15]. This arises from the fact that the input values are the possible amounts of gasoline that can be put into the tank...
Change the plotted equation to xcos(y)+ysin(x)=0 by using dot notation to set properties. Similarly, change the line color to red and line style to a dash-dot line. The horizontal and vertical lines in the output are artifacts that should be ignored. Get fi.Function = x/cos(y) ...
keywords, etc.) that are known to EES. Function calls show the needed inputs. The selected item can be entered into the Equations window saving you from having to type it in. This Auto Complete window also provides access to the online help for...
1.164a and 1.164b for the TE field), which dominates over the succeeding terms in the limit k→∞ (k0→∞ in the present notation) at any given point. Accordingly, these two terms, representing the TM and TE dipole fields of a harmonically varying localized charge-current distribution, ...
In this notation, ∇=(∂/∂x, ∂/∂y, ∂/∂z) E is the electric vector, B is the magnetic induction, ρ is the electric charge density, j is the electric current density,ε0 is the permittivity of free space, and c is the speed of light. In addition to Maxwell ...
