|X(f)|=|−jsin(2πfLTs)LTs|=|sin(2πfLTs)|LTs This equation shows that the magnitude spectrum, |X(f)|, is a sine function that goes to zero at f=1/(LTs)=fs/L. Figure 8.18 shows the frequency characteristics of the 2-point central difference algorithm for 2 different skip fa...
However, silicon can form indefinitely long chains, but with oxygen atoms to form a siloxane linkage (OSiO)n because of a very strong SiO bond energy (368 kJ/mol) [1]. That said, silicon compounds are more reactive than carbon compounds because of the presence of vacant 3d orbital. ...
Determine the directional derivative of f(x,y)=x+sin(xy) at (x,y)=(5,0) in the direction =⟨35,45⟩ Directional Derivative: To determine the directional derivative of the function f(x,y) we can perform the dot product of...
tanx=sinxcosx cotx=cosxsinx 3)cscx=1sinx,among others. Answer and Explanation:1 Let us find the derivative ofy=sec(x). Let's redefine the function as a function of cosine. Thus we have {eq}y = \dfrac{1}{\cos x}... ...
