SECTION – A 1. If A is a 3×3 invertible matrix, then what will be the value of k if det(A-1) = (detA)k .Solution: As | A-1 | = |A |-1 ∴ k = -1. 2. Determine the value of the constant ‘k’ so that f(x) =  is continuous at x = 0 .Solution:  3. Evaluate : Solution:  4. If […]

SECTION A Question numbers 01 to 04 carry 1 mark each. 1. State the reason why the relation R = {(a, b) : a ≤ b2} on the set R of real numbers is not reflexive.Sol. As 1/2 > (1/2)2 ⇒ (1/2 ,1/2) ∉ R. Hence R is not reflexive. 2. If A is a square matrix of order 3 […]

1. Let tan3x = t, then dt = 3 tan2x sec2x dx Answer. 2. Order = 2 and degree = 2 of given differential equation.Answer. order of given differential equation is 2. 1Also, the power of the highest order derivative is 2, hence the degree of differential equation is 2.Therefore, Order = 2 and Degree […]

1. Let √x = t and differentiate both sides.                                            ORUsing 1 = sin2x + cos2x and sin 2x = 2sin x cos x and solve it.Answer. 2. Used separable method, eydy = 2xex2 dx. and integrating both […]
