In maths textbooks, whenever we read the word ‘Log’, it feels like it is some alien idea that is not easy to understand. Students are often reluctant to explore the beautiful maths behind the logarithm and logarithmic functions. On the contrary, the concept of ‘Log’ or ‘Logarithm’ follows naturally into the minds when we understand … Read more
Forces A push or pull that accelerates an object having some mass is known as force. It is considered a vector quantity as it has both direction and magnitude. The SI unit of force is known as Newton (N). It is kg m/s2. a) Two skaters pushing the third skater in different directions with forces … Read more
Polynomial You must have heard the word ‘polynomial’ or a ‘polynomial equation’. Algebra is obsessed with polynomials. You will find them everywhere. So, what is a polynomial then? Polynomial is just an expression that involves variables and constants with arithmetic operators (‘+’, ‘-‘, ‘×’, ‘÷’) in between. An example of a polynomial is, As you … Read more
