A vector A has components Ax = -7.0 m and Ay = -48.0 m. What is the the angle that vector A makes with the x-axis?Vectors:Vectors are mathematical objects with an associated magnitude and direction. Thus they can be used to represent a ...

Sometimes we will refer only to the component of a vector quantity along a specific direction, which we will signify by a subscript and without boldface. Thus the velocity vector has components (vx, vy, vz)along the three Cartesian coordinates. The magnitude || of the velocity vector (which...
// This code doesn't compile even though Sprite is a DisplayObject subclass var v:Vector.<DisplayObject> = new Vector.<Sprite>(); 若要將具有基底類型T的 Vector 轉換為T之父類別的 Vector,請使用Vector()全域函數。 除了資料類型限制之外,Vector 類別的其他限制與 Array 類別還是有所區別的: ...
CLIC4 has been predicted as a direct target gene of the DREAM complex 40 and PCLAF 20 , and various DREAM components were recognized to bind the proximal promoter of CLIC4 (Supplementary Fig. 14B ). Thus, we tested whether PCLAF directly transactivates CLIC4 by chromatin immunoprecipitation ...
The components Ax,… are also useful for computing the result when vectors are added or multiplied by scalars. From the geometry in Cartesian coordinates, it is obvious that if C=kA+k′B, then C will have components Cx=kAx+k′Bx,Cy=kAy+k′By,Cz=kAz+k′Bz. At this stage it is con...
Since each normal mode has a known natural frequency, it is usually possible to omit those having natural frequencies well above any possible frequency components in the excitation, so reducing the number of equations. (4) Perhaps most important of all, the easiest method for validating a structu...
Thus, we can consider that the space vector fabc equals to the vector fdqs in the stationary reference frame, which has the d- and q-axes components of Eqs. (4.49) and (4.50) as (4.73)fdqs=fds+jfqs However, since the d–q axis may rotate at any angular velocity, we need to ...
