Is maths for JEE tough?
Students said Paper 1, held from 9 am to 12 pm, was moderate to difficult. While physics and chemistry were moderate, mathematics was relatively difficult, pointed out students. Paper 2, held from 2.30 pm to 5.30 pm, was moderately tough and the paper was lengthy compared to last year.
How do you solve a vector problem in math?
Example: Finding the Components of a Vector
- Draw the vector.
- Add in the triangle legs.
- Math. y-direction = magnitude * sin(angle) = 5 meters * sin (37) = 3 meters. x-direction = magnitude * cos(angle) = 5 meters * cos (37) = 4 meters.
- Plug the solutions into the definition of a vector. Vector = 3x̂ + 4ŷ Tada, easy as π!

Why is Maths important for the IIT JEE exam?
And, when it comes to the IIT JEE exam, Maths holds sheer importance. Practising Maths alongside other subjects (Physics, Chemistry) as much as possible will help you to secure the best possible rank in the JEE Mains exam.
Can a vector be written as a scalar multiple?
For example the vector in the figure can be written as the sum of the three vectors u1, u2, and u3, each along the direction of one of the base vectors e1, e2, and e3, so that It is clear from the figure that each of the vectors u1, u2 and u3 is parallel to one of the base vectors and can be written as a scalar multiple of that base.
How are the components of a vector multiplied?
Hence each component of a vector is multiplied by the scalar. If two vectors are of the same dimension then they can be added or subtracted from each other. The result is gain a vector. dd
