SS3 Mathematics Revision: Integration and Evaluation Simple Algebraic Functions

What is Algebraic Function? In mathematics, an algebraic function is a function that can be defined as the root of a polynomial equation. Quite often algebraic functions can be expressed using a finite number of terms, involving only the algebraic operations addition, subtraction, multiplication, division, and raising to a fractional power. Examples of such functions are: Some [...]

SS2 Physics Third Term: Sound Wave

The Velocity of Sound Waves Since there are three states of matter, it means there must be three velocities for the three states, because experimentally three states are not the same. The velocity varies from medium to medium. The velocity of sound in air, for dry air at 00C is approximately 330m/s, but at room [...]
