Calculus
using cartesian vectors ** forgot to include that.

Calculus
determine the each resultant a) 10 km/h north followed by 8 km/h west b) 25 N at 10 degrees to the horizontal and 30 N horizontally.

Calculus
three forces each of magnitude 50 N, act in eastward, westward, and northwest directions, Find the resultant force.

Calculus
determine the angle between the planes 2x + 2y + 7z = 8 and 3x - 4y + 4z = 5

Calculus / a bit of physics
explain why a scalar equation of the line exists in 2-D space, but not in 3-D space.

Calculus
determine an equation for each plane a) contains the point A(6,2,3), B(5,1,-3), and C(5,7,-2) b) parallel to 2x + 6y + 4z = 1 and contains the point P(3,2,1)
