Let's quickly go over few important maths formulas class 12 from the syllabus:


Vectors and Three Dimensional Geometry Formulas for Class 12

  1. Position Vector - $ \overrightarrow{OP}=\vec{r}=\sqrt{x^{2}+y^{2}+z^{2}}$

  2. Direction Ratios - $ l=\dfrac{a}{r},m=\dfrac{b}{r},n=\dfrac{c}{r}$

  3. Vector Addition - $\vec{PQ}+\vec{QR}=\vec{PR}$

  4. Commutative Property - $ \vec{a}+\vec{b}=\vec{b}+\vec{a}$

  5. Associative Property - $\left (\vec{a}+\vec{b} \right )+\vec{c}=\vec{a}+\left (\vec{b}+\vec{c} \right )$

  6. Vector Joining Two Points - $\overrightarrow{P_{1}P_{2}} = \overrightarrow{OP_{2}} - \overrightarrow{OP_{1}}$

  7. Skew Lines - $\cos\theta = \left | \dfrac{a_{1}a_{2}+b_{1}b_{2}+c_{1}c_{2}}{\sqrt{a_{1}^{2}+b_{1}^{2}+c_{1}^{2}}\sqrt{a_{2}^{2}+b_{2}^{2}+c_{2}^{2}}} \right |$

  8. Equation of a Line - $\dfrac{x-x_{1}}{a}=\dfrac{y-y_{1}}{b}=\dfrac{z-z_{1}}{c}$

  9. Distance between two points in 3D: $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2 + (z_2 - z_1)^2}$

  10. Distance Formula: $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

  11. Midpoint Formula: $(x_m, y_m) = \left( \dfrac{x_1 + x_2}{2},  \dfrac{y_1 + y_2}{2}\right)$


Algebra Formulas For Class 12

  1. If you have a vector $\vec{a}=x\hat{i}+y\hat{j}+z\hat{k}$, then you can find its length by using the formula $\left | \overrightarrow{a} \right | = a =\sqrt{x^{2}+y^{2}+z^{2}}$. This length is also called the magnitude, norm, or absolute value of the vector.

  2. A unit vector is a vector with a length of 1. If you have a vector $\vec{a}$  its unit vector is denoted as $\hat{a}$ is calculated as $\hat{a}=\dfrac{\vec{a}}{\left | \vec{a} \right |}$

  3. Some important unit vectors are $\hat{i}, \hat{j}, \hat{k}$, where $\hat{i} = [1,0,0],\: \hat{j} = [0,1,0],\: \hat{k} = [0,0,1]$

  4. If you have directional angles $\alpha, \beta, \gamma$ represented by $l=\cos \alpha, m=\cos \beta, n=\cos\gamma$, respectively, they are called directional angles of the vector $\overrightarrow{a} $. Additionally, the relationship $\cos^{2}\alpha + \cos^{2}\beta + \cos^{2}\gamma = 1$ holds for these directional angles.

  5. Quadratic Formula: $x =  \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

  6. Arithmetic Progression (AP):

  • $a_n = a + (n-1)d$

  • $S_n =  \dfrac{n}{2}[2a + (n-1)d]$

  • $S_n =  \dfrac{n}{2}[a + l]$

  1. Geometric Progression (GP):

  • $a_n = ar^{(n-1)}$

  • $S_n =  \dfrac{a(r^n - 1)}{r - 1}$


Vector Addition Formulas for Class 12

  1. $\vec{a}+\vec{b}=\vec{b}+\vec{a}$

  2. $\vec{a}+\left ( \vec{b}+ \vec{c} \right )=\left ( \vec{a}+ \vec{b} \right )+\vec{c}$

  3. $k\left ( \vec{a}+\vec{b} \right )=k\vec{a}+k\vec{b}$

  4. $\vec{a}+\vec{0}=\vec{0}+\vec{a}$,  therefore $\vec{0}$  is the additive identity in vector addition.

  5. $\vec{a}+\left ( -\vec{a} \right )=-\vec{a}+\vec{a}=\vec{0}$, therefore $-\vec{a}$  is the inverse in vector addition.


Calculus Formulas for Class 12

Maths formulas can be extremely difficult to understand and revise. However, there’s no shortcut to revising maths formulas. Students have to regularly jot down the formulas and memorize them to ensure that they don’t forget the formulas before their exams. Students must avoid mugging up these formulas right before exams as they may not only forget the formulas but also jumble up the formulas. Thus, students must take time out to understand how formulas are created. This can sound illogical but can help students learn how to derive the formulas.

2. Why Should You Refer to Class 12 Maths Formulas?

The prime perk of referring to the class 12 maths formula PDF is eliminating the need to recite problems and learn how to solve them instead. Students can directly refer to these formulas instead of going through the textbooks to save time to prepare well for their exams. Writing down each one of these formulas can be a tedious task. However, referring to them online can help you encounter a fun-loving and inspiring learning experience.

3. How many formulas do I need to remember for the Class 12 Maths exam?

4. What are some tips for memorizing maths formulas class 12 effectively?

Here are some tips for memorizing formulas effectively:


  • Don't just memorize the formula, try to understand the logic and derivation behind it. This will help you recall the formula more easily and apply it correctly.

  • Solve problems from your textbook or other resources that involve the formulas you want to learn. This will help solidify your understanding and build confidence in using them.

  • Organize the formulas in a way that works for you, like flashcards or mind maps. This can help visualize the relationships between different formulas and make them easier to remember.

  • Don't try to cram all the formulas the night before the exam. Regularly revise them throughout your preparation to ensure they stay fresh in your memory.

5. Are there any maths formulas class 12 that are more important than others?

While every formula has its place, some formulas are used more frequently or are crucial for specific topics. Focus on understanding formulas in these areas:


  • Algebra: Quadratic equations, complex numbers, permutations and combinations.

  • Calculus: Differentiation and integration rules, applications of derivatives and integrals.

  • Vectors and 3D Geometry: Dot product, cross product, distance formula, direction cosines.
