Also, since both the tangent and. cotangent cotangent functions are ratios of an odd function. and and an even function then both the tangent and. cota cotangent functions are odd functions (graph is. symm symmetric about the origin). We first sketch the graph of tangent. Since it has period Ã¨, we need only sketch the graph on. any interval of length Ã¨ and then repeat the pattern to the left and to the right.
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia.
First law of motion - The first law of motion states that any object in motion will continue to move in the same direction and speed unless external forces act on it. Force - Force is the measurement of a push or pull on an object. Force is a vector measured in newtons. Friction - Friction is the resistance of motion when one object rubs against another. It is a force and is measured in newtons. Gravity - Gravity is a force caused when the mass of physical bodies attract each other.
