The curve is symmetricabout the x-axis
The Cartesian coordinate (rectangular coordinates) system is right-handed.
The three coordinate planes x = 0, y = 0 and z = 0 dividespace into eight cells called octants.
The octant in which the point coordinates are allpositive is called the first octant;
There is no conventional numbering for the other sevenoctants.
• Some of the things are determinedsimply by their magnitudes. To recordmass, length, or time
• only write down a number and name anappropriate unit of measure.
• more information required to describe aforce, displacement, or velocity.
• We need to record the direction inwhich it acts as well as how large it is.
Find,
• how to calculate the angle between twovectors directly from their components.
• A key part of the calculation is anexpression called the dot product.
• also called inner or scalar productsbecause the product results in a scalar,not a vector. finding the projection of onevector onto another
Torque
When we turn a boltby applying a force Fto a wrench, thetorque we produceacts along the axis ofthe bolt to drive thebolt forward
