List of Maths Formulas for 11th Class

List of maths formulas for 11th class includes important formulas from chapters like Algebra, Trigonometry, Calculus, Coordinate Geometry, and Statistics. When you understand these formulas properly, your speed and accuracy while solving questions improve greatly.

Moreover, basic math formulas also help a lot in competitive exams like JEE and NEET, where solving problems within the time limit is very important. For your reference and quick access, find out the Class 11 Maths formulas list here:

A U B = {x: x ∈ A (or) x ∈ B}
A ∩ B = {x: x ∈ A (and) x ∈ B}

A × B = {(a, b): a ∈ A, b ∈ B}
sin(x + y) = sin(x) cos(y) + cos(x) sin(y)
cos(x + y) = cos(x) cos(y) - sin(x) sin(y)
tan(x + y) = (tan(x) + tan (y)) / (1- tan(x) × tan(y))
sin(x - y) = sin(x) cos(y) - cos(x) sin(y)
cos(x - y) = cos(x) cos(y) + sin(x) sin(y)
tan(x - y) = (tan(x) - tan (y)) / (1 + tan(x) × tan(y))
limx → a(xn - an) / x - a = nan - 1
limx → a sinx / x = 1
limx → a 1 - cosx / x = 0
f ´( x ) = d f(x)/dx = limh → 0 [ f(x + h) - f(x) / h]
x̅ = ∑|xi - x̅| / n
σ2 = ∑fi(xi - x̅)2/ N

Class 11 Math Formula Sheet for Trigonometry

Trigonometry in maths is about the relationship between the sides and angles of a right-angled triangle. In class 11, you learn many important trigonometric formulas that help you solve questions efficiently. Here are some important formulas from the class 11 math formula sheet for trigonometry:

sin(90° - A) = cos A
cos(90° - A) = sin A
tan(90° - A) = cot A
cot(90° - A) = tan A
sec(90° - A) = cosec A
cosec(90° - A) = sec A
sin2 θ + cos2 θ = 1 ⇒ sin2 θ = 1 - cos2 θ ⇒ cos2 θ = 1 - sin2 θ
cosec2 θ - cot2 θ = 1 ⇒ cosec2 θ = 1 + cot2 θ ⇒ cot2 θ = cosec2 θ - 1
sec2 θ - tan2 θ = 1 ⇒ sec2 θ = 1 + tan2 θ ⇒ tan2 θ = sec2 θ - 1
sin θ cosec θ = 1 ⇒ cos θ sec θ = 1 ⇒ tan θ cot θ = 1

List of Maths Formulas for 11th Class from Calculus

Calculus is a branch of mathematics that plays an important role in many other subjects like physics, biology, chemistry, and economics. In class 11, Calculus is about understanding how a function’s value changes when the input changes. You can do this study of change using derivatives, which are some of the important concepts in calculus.

The formulas related to derivatives are very important because they are used in many areas of mathematics and science. Find the list of maths formulas for 11th class from Calculus that every student must learn and remember:

d/dx [f(x) + g (x)] = d/dx [f(x)] + d/dx [g(x)] (Derivative of a sum)
d/dx [f(x) - g (x)] = d/dx [f(x)] - d/dx [g(x)] (Derivative of a difference)
d/dx [f(x) × g (x)] = d/dx [f(x)] × [g(x)] + [f(x)] × d/dx [g(x)] (Derivative of a product)
d/dx [f(x) / g (x)] = {d/dx [f(x)] × [g(x)] - [f(x)] × d/dx [g(x)]} / g(x)2 (Derivative of a quotient)
