Question 3(xviii)
Verify Rolle’s theorem for function f(x) = sin x – sin 2x on [0, pi] on the indicated intervals.Solution 3(xviii)
Question 7
Solution 7
x = 0 then y = 16
Therefore, the point on the curve is (0, 16) Question 8(i)
Solution 8(i)
x = 0, then y = 0
Therefore, the point is (0, 0)Question 8(ii)
Solution 8(ii)
Question 8(iii)
Solution 8(iii)
x = 1/2, then y = – 27
Therefore, the point is (1/2, – 27)Question 9
Solution 9
Question 10
Solution 10
Question 11
Solution 11
Question 2(ii)
Verify Rolle’s theorem for each of the following functions on the indicated intervals:
Solution 2(ii)
Given function is
As the given function is a polynomial, so it is continuous and differentiable everywhere.
Let’s find the extreme values
Therefore, f(2) = f(6).
So, Rolle’s theorem is applicable for f on [2, 6].
Let’s find the derivative of f(x)
Take f'(x) = 0
As 4 ∈ [2, 6] and f'(4) = 0.
Thus, Rolle’s theorem is verified.
