Exercise 6.4 Class 12 NCERT Solutions Question 2.<\/strong>
\nFind the approximate value of f (2.01), where f (x) = 4x\u00b2 + 5x + 2
\nSolution:
\nf(x+\u2206x) = f(2.01), f(x) = f (2) = 4.2\u00b2 + 5.2 + 2 = 28,
\nf’ (x) = 8x + 5 Now, f(x + \u2206x) = f(x) + \u2206f(x)
\n= f(x) + f’ (x) . \u2206x = 28 + (8x + 5) \u2206x
\n= 28 + (16 + 5) x 0.01
\n= 28 + 21 x 0.01
\n= 28 + 0.21
\nHence, f(2.01) \u2248 28 x 21.<\/p>\n

6.4 Class 12 NCERT Solutions Question 3.<\/strong>
\nFind the approximate value of f (5.001), where f(x) = x3<\/sup> – 7x2<\/sup> +15.
\nSolution:
\nLet x + \u2206x = 5.001, x = 5 and \u2206x = 0.001,
\nf(x) = f(5) = – 35
\nf(x + \u2206x) = f(x) + \u2206f(x) = f(x) + f'(x).\u2206x
\n= (x3<\/sup> – 7x\u00b2 + 15) + (3x\u00b2 – 14x) \u00d7 \u2206x
\nf(5.001) = – 35 + (3 \u00d7 5\u00b2 – 14 \u00d7 5) \u00d7 0.001
\n\u21d2 f (5.001) = – 35 + 0.005
\n= – 34.995.<\/p>\n

Exercise 6.4 Class 12 Maths Question 4.<\/strong>
\nFind the approximate change in the volume V of a cube of side x metres caused by increasing the side by 1%.
\nSolution:
\nThe side of the cube = x meters.
\nIncrease in side = 1% = 0.01 \u00d7 x = 0.01 x
\nVolume of cube V = x3<\/sup>
\n\u2234 \u2206v = \\(\\frac { dv }{ dx }\\) \u00d7 \u2206x
\n= 3x\u00b2 \u00d7 0.01 x

Class 12 Maths Ex 6.4 Solutions Question 5.<\/strong>
\nFind the approximate change in the surface area of a cube of side x metres caused by decreasing the side by 1%.
\nSolution:
\nThe side of the cube = x m;
\nDecrease in side = 1% = 0.01 x
\nIncrease in side = \u2206x = – 0.01 x
\nSurface area of cube = 6x\u00b2 m\u00b2 = S
\n\u2234 \\(\\frac { ds }{ dx }\\) \u00d7 \u2206x = 12x \u00d7 (- 0.01 x)

\nIf the radius of a sphere is measured as 7m with an error of 0.02 m, then find the approximate error in calculating its volume.
\nSolution:
\nRadius of the sphere = 7m : \u2206r = 0.02 m.
\nVolume of the sphere V = \\(\\frac { 4 }{ 3 } \\pi { r }^{ 3 }\\)
\n\\(\\Delta V=\\frac { dV }{ dr } \\times \\Delta r=\\frac { 4 }{ 3 } .\\pi .3{ r }^{ 2 }\\times \\Delta r\\)

Ex6.4 Class 12 NCERT Solutions Question 7.<\/strong>
\nIf the radius of a sphere is measured as 9 m with an error of 0.03 m, then find the approximate error in calculating its surface area.
\nSolution:
\nRadius of the sphere = 9 m: \u2206r = 0.03m
\nSurface area of sphere S = 4\u03c0r\u00b2
\n\u2206s = \\(\\frac { ds }{ dr }\\) \u00d7 \u2206r
\n= 8\u03c0r \u00d7 \u2206r
\n= 8\u03c0 \u00d7 9 \u00d7 0.03
\n= 2.16 \u03c0m\u00b2.<\/p>\n

Question 8.
\nIf f (x) = 3x\u00b2 + 15x + 5, then the approximate value of f (3.02) is
\n(a) 47.66
\n(b) 57.66
\n(c) 67.66
\n(d) 77.66
\nSolution:
\n(d) x + \u2206x = 3.02, where x = 30, \u2206x = 0.2,
\n\u2206f(x) = f(x + \u2206x) – f(x)
\n\u21d2 f(x + \u2206x) = f(x) + \u2206f(x) = f(x) + f'(x) \u2206x
\nNow f(x) = 3×2 + 15x + 5; f(3) = 77, f’ (x) = 6x + 15
\nf’ (3) = 33
\n\u2234 f (3.02) = 87 + 33 x 0.02 = 77.66<\/p>\n

\n(b) 0.6 x\u00b3 m\u00b3
\n(c) 0.09 x\u00b3 m\u00b3
\n(d) 0.9 x\u00b3 m\u00b3
\nSolution:
\n(c) Side of a cube = x meters
\nVolume of cube = x\u00b3,
\nfor \u2206x \u21d2 3% of x = 0.03 x
\nLet \u2206v be the change in v0l. \u2206v = \\(\\frac { dv }{ dx }\\) x \u2206x = 3x\u00b2 \u00d7 \u2206x
\nBut, \u2206x = 0.03 x
\n\u21d2 \u2206v = 3x\u00b2 x 0.03 x
\n= 0.09 x\u00b3m\u00b3<\/p>\n","protected":false},"excerpt":{"rendered":"
