Find the solution of the system x′=−4y,y′=−2x, where primes indicate derivatives with respect to t, that satisfies the initial c

Andreas93 [3]

Answer: $2y^2 = x^2+4$

Step-by-step explanation:

given is a differntial equation in parametric form as

$x'=-4y\\y'=-2x$

We can find dy/dx by dividing y' by x'

$\frac{dy}{dx} =\frac{-2x}{-4y} \\4ydy =2x dx\\2y^2 = x^2+C$

(By separating the variables and integrating)

C is arbitrary constant

When x=-2, y =-2

Substitute to get

$8=4+C\\C=4$

So solutoin is

$2y^2 = x^2+4$

is the solution

Answer:

Step-by-step explanation:

Hey There!

So if you didn't know angle H is a right angle. So we are given two angles and they want us to find the missing angle

Remember all of the angles of a triangle add up to equal 180

so we subtract the given angles from 180 to find the missing angle

180-90-68=22

so we can conclude that angle G = 22
