How do you multiply

(9 - i) (7 - 3 i)

in trigonometric form?

https://socratic.org/questions/how-do-you-multiply-9-i-7-3i-in-trigonometric-form

21189 (cos (α + β) + i sin (α + β))

α = tan^{- 1} (- \frac{1}{9})

(5, 9) - (- 5, - 5)

https://www.tiger-algebra.com/drill/(5,9)-(-5,-5)/

Finding the distance, midpoint, slope, equation and the x y-intercepts of a line passing between the two points p1 (5,9) and p2 (-5,-5)The distance (d) between two points (x1,y1) and (x2,y2) is given ...

A = < 4, 2, - 5 >

B = < 6, 5, 9 >

C = A - B

, what is the angle between A and C?

https://socratic.org/questions/if-a-4-2-5-b-6-5-9-and-c-a-b-what-is-the-angle-between-a-and-c

= 54.7

º Explanation: Let's start by calculating

C = A - B

C = 〈 4, 2, - 5 〉 - 〈 6, 5, 9 〉 = 〈 - 2, - 3, - 14 〉

What is the slope of the line passing through the following points:

(- 7, - 2), (- 3, 8)

https://socratic.org/questions/what-is-the-slope-of-the-line-passing-through-the-following-points-7-2-3-8

See a solution process below: Explanation:

m = \frac{( y _{2} ) - ( y _{1} )}{( x _{2} ) - ( x _{1} )}

(x_{1} y_{1})

What is the unit vector that is orthogonal to the plane containing

(29 i - 35 j - 17 k)

(41 j + 31 k)

https://socratic.org/questions/what-is-the-unit-vector-that-is-orthogonal-to-the-plane-containing-29i-35j-17k-a

The unit vector is

= \frac{1}{1 5 4 0 . 3} 〈 - 388, - 899, 1189 〉

Explanation: The vector perpendicular to 2 vectors is calculated with the determinant (cross product)

∣ ∣ ∣ ∣ ∣ ∣ ∣ i d g j e h k f i ∣ ∣ ∣ ∣ ∣ ∣ ∣

Combined Gravitational Force Vectors in a Spherical Coordinate System

https://physics.stackexchange.com/questions/29092/combined-gravitational-force-vectors-in-a-spherical-coordinate-system

Not to worry, you've explained your question fine. However, your lack of familiarity with vectors is probably making this a lot more complicated than it could be. Anyway, to get to the point: the ...
