Here it is exactly:
Formulate the following problems in Matrix-difference equation
xn+1 = Axn and specify the components of x
(2) Each number is the average of the two previous numbers.
Problem: Each number is the average of the previous two numbers.
I am guessing I need to find a matrix A that when multiplied by a vector x, it will return another vector with its entries as the averages. Is this correct? Need some hints on how to start this one.
I am trying to rewrite -i arctan ix = arctanh x + c as
e^it = cos t + i sin t
I am having trouble rewriting
sqrt[ 1 + i tan t / 1 - i tan t]
as
cos t + i sin t
Is this possible or did I do something wrong?
What do I multiply the sqrts by.
I need help getting the integral of
1/x^(1+a)
I tried using substitution but it didnt work.
I keep getting x/a. Could someone show
me what I am doing wrong.
I am having trouble solving for the two values
of (x) that are closest to zero.
-30 sin 3x = 1/10 cos 3x
Is there a formula I could use to make this easy?
