Class 12 Exercise 1.2 of Maths Chapter 1 - Relation and Functions, is crucial for a solid foundation in math. Understanding the concept of the fundamental principles of relations and functions. Where students gain a deeper understanding of functions, a special type of relation where each input (...
In other words, a function f is a relation from a set A to a set B where the domain of f is A and no two distinct ordered pairs in f share the same first element. A and B are also two non-empty sets. We provide RD Sharma solutions for class 12 maths chapter 2 – functions t...

Unsurprisingly, some poets were unsure if what they sent in could be described as ‘radical’. Others, like Gina Paola Ritch, were very clear: “Is [the radical aspect] the subject matter or the style in relation to ‘cosy reading of traditional themes’? And does poetry highlighting social...
Some common moves in relation to this goal are the following: asking students to repeat, revoice, or clarify; summarizing a lengthy discussion; doing a piece of mathematics; making connections; drawing attention to specific ideas; and controlling the pace of the discussion (Jacobs & Spangler, ...
