उत्तर
Given function h(x) = sin (2x) + 5
We know that -1 ≤ sin 2x ≤ 1
⇒ 4 ≤ 5 + sin 2x ≤ 6
Maximum value of sin 2x = 1
∴ h(x) = Maximum value of sin 2x + 5, 1 + 5 = 6
Minimum value of sin 2x = - 1
∴ h(x) = Minimum value of sin 2x + 5 = -1 + 5 = 4

Complete the following activity to divide 84 into two parts such that the product of one part and square of the other is maximum.
Solution: Let one part be x. Then the other part is 84 - x
Letf (x) = x2 (84 - x) = 84x2 - x3
∴ f'(x) = `square`
and f''(x) = `square`
For extreme values, f'(x) = 0
∴ x = `square "or" square`
f(x) attains maximum at x = `square`
Hence, the two parts of 84 are 56 and 28.
