Soln: Actually, antiderivatives is the reserve of derivative. If f(x) and F(x) are the functions of x such that (F(x)) then the antiderivative of f(x) with respect to x is th function F(x) and is written as: Or, .dx = F(x) If c is constant quantity and derivative of a constant quantity is zero, then, Or, (F(x) + c) = f(x) Hence, .dx = F(x) + c. Since, c is an unknown constant and it may be any real number, so there are a number of antiderivatives of function whoch are different from one another by a constant. Let us see the following example: If y = x be the given function then, Or, (x ) = 2x, then dx = x Similarly, (x + 1) = 2x, then + 1 Or, = 2x, then + . If a is constant, (x + a) = 2x, then = x + a and so on. Above examples show that there are a number of antiderivatives of 2x which are different from one another by constant. d dx ∫ f(x) d dx ∫ f(x) 2 d dx 2 ∫ 2x. 2 d dx 2 ∫ 2x.dx = x 2 ( + ) d dx x 2 3 5 ∫ 2x.dx = x 2 3 5 d dx 2 ∫ 2x.dx 2 Go Top  Home (http://www.khullakitab.com/) Grade 11 (grade-11/subjects/solutions) Mathematics (mathematics/publications/grade-11/12/solutions) Sukunda Pustak Bhawan Antiderivatives and Its Application.    

Soln: If f(x) and F(x) are two functions such that (F(x)) = f(x) then (F(x) + c) = f(x) as derivative of a constant ter is zero, so Or, .dx = F(x) + c Where, c is an arbitrary constant. Since this constant is the unknown quantity, so it is known as the indefini integral. The integral of a function independent of arbitrary constant is known as definite integral. The indefinite integral contains an arbitrary constant where definite integral does not. .dx is the definit integral of f(x) w.r.t. ‘x’ between the limits a and b. b is the upper limit ad a is the lower limit. This gives the are bounded by the curve y = f(x), x – axis and the two ordinates x = a and x = b. 3. (i) Soln: = .dx = .dx = .dx = + 3logx + + c. = x + x + 3logx – + c.
