• Slope of tangent (m_t = f'(x_0))
• Equation of tangent: (y - y_0 = m_t (x - x_0))
• Slope of normal: (m_n = -1/m_t) (if (m_t \neq 0))
• Equation of normal: (y - y_0 = m_n (x - x_0))

8. Parametric Differentiation

Unlike academic monographs intended for university-level pure mathematics (such as Spivak or Apostol), Vinay Kumar’s work is utilitarian and problem-solving oriented. It bridges the gap between board exam concepts and the rigorous application required for entrance tests. vinay kumar differential calculus pdf
