Topics covered in Limits And Derivatives for MHT-CET Mathematics.
Topics in Limits And Derivatives
1
12.1 Introduction to Limits
- A limit describes the value a function approaches as the input approaches a specific value
- Limits exist even when the function is not defined at that point
- Left-hand limit (LHL) and right-hand limit (RHL) must be equal for a limit to exist
2
12.2 Algebra of Limits
- Sum rule: lim[f(x) + g(x)] = lim f(x) + lim g(x)
- Product rule: lim[f(x) × g(x)] = lim f(x) × lim g(x)
- Quotient rule: lim[f(x)/g(x)] = lim f(x) / lim g(x), provided lim g(x) ≠ 0
3
12.3 Limits of Polynomial and Rational Functions
- For polynomial functions: lim(x→a) p(x) = p(a) (direct substitution)
- For rational functions: lim(x→a) p(x)/q(x) = p(a)/q(a) if q(a) ≠ 0
- Important result: lim(x→a) (x^n - a^n)/(x - a) = na^(n-1)
4
12.4 Trigonometric Limits
- Fundamental limit: lim(x→0) (sin x)/x = 1
- Related limits: lim(x→0) (tan x)/x = 1, lim(x→0) (1 - cos x)/x² = 1/2
- Squeeze theorem is often used for trigonometric limits
