In this article, we will look at standard identities as well as some other Algebraic identities. In addition, we will attempt to derive these identities without using the binomial theorem. We’ll also look at some solved examples of problems that use these mathematical identities to solve them. What is an Algebraic Identity An Algebraic identity […]

Students can get trigonometry formulas for Class 10 here. Trigonometry is the study of the relationships between triangle angles, lengths, and heights. It contains ratios, functions, identities, and formulas for solving issues based on right-angled triangles. Trigonometry is also used in engineering, astronomy, physics, and architectural design. This chapter is crucial since it covers a

Quantum numbers are numerical values that describe the properties of atomic orbitals and the electrons in those orbitals. They are essential for understanding the arrangement of electrons in atoms and the resulting chemical behavior of elements. There are four primary quantum numbers: principal (n), azimuthal (l), magnetic ($m_l$), and spin ($m_s$). Here is the chart
