Answer:
The given power series
is a solution of the differential equation (1+x^2)y' + 2xy = 0
Step-by-step explanation:
This is a very trivial exercise, follow the steps below for the solution:
Step 1: Since n = 0, 1, 2, 3, 4, ........, Substitute the values of n into equation (1) below.
.....................(1)

Step 2: Find the derivative of y, i.e. y'

Step 3: Substitute y and y' into equation (2) below:

(Verified)
Since the LHS = RHS = 0, the given power series
is a solution of the differential equation (1+x^2)y' + 2xy = 0
I think that's false
Step-by-step explanation:

Tanx-5=0
tanx=5
tan inverse (5)=x
78.69
Mean 60 - 2(0.9) = 58.2
58.2 is 2 standard deviations from the mean.
Answer:
Solve the 1st equation for y and then you substitute the answer of the y value to the other equation to get the x value
