Integrate the following with respect to x:<\/p>\n
Question 1.
\n(i) 9x e3x<\/sup>
\nAnswer:
\n
\n<\/p>\n<\/p>\n
(ii) x sin 3x
\nAnswer:
\n<\/p>\n
<\/p>\n
(iii) 25 x e-5x<\/sup>
\nAnswer:
\n
\n<\/p>\n<\/p>\n
(iv) x sec x tan x
\nAnswer:
\n\u222b x sec x tan x dx
\nu = x, u’ = 1 , u” = 0
\ndv = sec x tan x dx , v = \u222b sec x tan x dx = sec x
\nv1<\/sub> = \u222b v dx = \u222b sec x dx = log |sec x + tan x|
\nv2<\/sub> = \u222b v1<\/sub> dx = \u222b log |sec x + tan x| dx
\n\u222b u dv = uv – u’ v1<\/sub> + u” v2<\/sub> – u”’ v3<\/sub> + ………….
\n\u222bx sec x tan x dx = x sec x – 1 \u00d7 log |sec x + tan x| + 0 \u00d7 \u222b log |x sec x tan x| + c
\n\u222bx sec x tan x dx = x sec x – log |sec x + tan x| + c<\/p>\nQuestion 2.
\n(i) x log x
\nAnswer:
\n
\n<\/p>\n
<\/p>\n
<\/p>\n
(ii) 27 x2<\/sup> e3x<\/sup>
\nAnswer:
\n<\/p>\n<\/p>\n
(iii) x2<\/sup> cos x
\nAnswer:
\n<\/p>\n(iv) x3<\/sup> sin x
\nAnswer:
\n\u222b x3<\/sup> sin x
\nu = x3<\/sup>, u’ = 3x2<\/sup>, u” = 6x , u”’ = 6 , u’v<\/sup> = 0
\ndv = sin x dx \u21d2 v = \u222b sin x dx = – cosx
\nv1<\/sub> = \u222bv dx = \u222b- cos x dx = – \u222b cos x dx = – sin x
\nv2<\/sub> = \u222b v1<\/sub> dx = \u222b – sin x dx = – \u222b sin x dx = – (- cos x) = cos x
\nv3<\/sub> = \u222b v2<\/sub> dx = \u222b cos x dx = sin x
\nv4<\/sub> = \u222b v3<\/sub> dx = \u222b sin x dx = – cos x
\n\u222b u dv = uv – u’ v1<\/sub> + u” v2<\/sub> – u”’ v3<\/sub> + u’v<\/sup>v4<\/sub> – ………..
\n\u222bx3<\/sup> sin x dx = x3<\/sup> (- cos x) – 3x2<\/sup> (- sin x) + 6x (cos x) – 6 sin x + 0 (- cos x) + c
\n= -x3<\/sup> cos x + 3x2<\/sup> sin x + 6x cos x – 6 sin x + c<\/p>\n<\/p>\n
Question 3.
