Solve complimentary function: Let y = emx then, d2y/dx2 - 5dy/dx + 4y = 0 m2emx - 5memx + 4emx = 0 (substituting fo...
The largest speed is obtained at the position of equilibrium.
v=Aw
So v= 2 x 1
v=2ms-1
To identify a Poisson distribution question, remember that in a Poisson distribution... Events occur independently of each other Events occur at a constant rate Events occur singly (that is, two can't hap...
You're right, when you first learn about matrix multiplication it definitely doesn't feel like the easiest way of defining a form of multiplication. This is particularly true if you've just lear...
The gradient of the line is given by change in Y divided by change in X. To find the Y value of the point we must put 2+h into the y=(2-x)(1+x)+3. Doing this we get y=(2-(2+h))(1+(2+h))+3=(-h)(3+h)+3= -3h...
