**r**is a vector while r is a scalar.

## Homework Statement

given that, relative to the geocentric equatorial frame,

**r**=-6634.2

**i**-1261.8

**j**-5230.9

**k**[km]

the eccentricity vector is

**e**=-0.40907

**i**-0/48751

**j**-0.63640

**k**

and the satellite is flying towards perigee, calculate the inclination of the orbit.

## Homework Equations

eq1:

**e**=1/u*(

**v**X

**h**-

**r**/r

eq2:

**h**=

**r**X

**v**

formular for inclination is i=arccos(

**h**.

**k**/h)

## The Attempt at a Solution

i managed to find

**v**X

**h**using eq1,

since

**r**.(

**v**X

**h**=

**h**.(

**r**X

**v**=

**h**.

**h**=h^2

so i find h, but idk how can i find the vector

**h**. anyone have a better approach?
