Questions: How many formulas can you find in class 12 CBSE Maths.

Ans: It is nearly impossible to keep track of all formulas in the Maths book for class 12 CBSE. Each theory and concept in the book has one or more formulas that can be used to solve the mathematical problem. The difficulty of mathematics at the school level is made more difficult by the increasing number of formulas.

Ques: Why is it important to use mathematical formulas?

Ans: Mathematical formulas are crucial because they help in solving mathematical problems with ease. These mathematical formulas are essential for solving problems within a specified time frame and in an efficient way. The generalized form of mathematical formulas is used to solve mathematical problems. All we have to do is add the value of the entities into the formula and speed up the process.

Ques: What is the formula used for the trigonometric ratio integration?

Ans: ∫sin (x) dx = -Cos x + C

∫cos(x) dx = Sin x + C

∫sec^2x dx = tan x + C, etc.

Ques: What is the formula used for the exponential function integration?
