FAQs on JEE Main 2025-26 Mock Test 1-2: Differential Equations Practice
1. What is a linear equation in one variable?
A linear equation in one variable is an algebraic equation that can be written in the form ax + b = 0, where a and b are real numbers and x is the variable. It represents a straight line and has only one solution for the value of x.
2. How do you solve a linear equation in one variable?
To solve a linear equation in one variable, isolate the variable by performing inverse operations on both sides of the equation. The general steps are:
- Move variables to one side and constants to the other.
- Combine like terms if necessary.
- Divide or multiply to get the value of the variable.
3. What is a system of linear equations?
A system of linear equations is a set of two or more linear equations involving the same set of variables. The solution to the system is the set of variable values that satisfy all equations simultaneously.
4. What are the methods to solve a system of linear equations?
Common methods for solving a system of linear equations include:
- Substitution method
- Elimination method
- Graphical method
5. How do you identify if a given equation is linear?
An equation is linear if the variable(s) have only power 1 (degree 1) and there are no products, roots, or higher powers of the variables. In general, a linear equation has the form ax + by + c = 0 (for two variables).
6. What is a first order differential equation?
A first order differential equation is a mathematical equation that relates a function with its first derivative. It is usually written as dy/dx = f(x, y), and describes how the function changes with respect to its variable.
7. What is the difference between a linear and a nonlinear differential equation?
A linear differential equation contains the unknown function and its derivatives to the first power and does not involve products or nonlinear functions (like sin or exp) of the function or its derivatives. A nonlinear differential equation involves higher powers, products, or other nonlinear terms.
8. How do you solve a basic first order linear differential equation?
A first order linear differential equation is of the form dy/dx + P(x)y = Q(x). The standard method to solve it is:
- Find the integrating factor (I.F.): I.F. = exp(∫P(x)dx)
- Multiply both sides by the integrating factor.
- Integrate both sides and solve for y.
9. What are the real-life applications of linear equations?
Linear equations are used in various fields such as economics (to solve supply and demand problems), physics (to describe motion), engineering (to model electrical circuits), and daily life situations like budgeting and finance calculations.
10. What is the general solution of a linear differential equation?
The general solution of a linear differential equation includes a family of functions that satisfy the equation, usually expressed with an arbitrary constant C. Particular solutions are found by applying initial or boundary conditions.
11. Can a linear equation have more than one solution?
A single linear equation in one variable has only one solution. However, a system of linear equations may have one solution (consistent), no solution (inconsistent), or infinitely many solutions (dependent system).
12. What is the order and degree of a differential equation?
The order of a differential equation is the highest derivative present in the equation. The degree is the exponent of the highest order derivative, provided the equation is polynomial in derivatives. For example, in d2y/dx2 + dy/dx = 0, the order is 2 and the degree is 1.
