\n(d) 42<\/p>\n

\nAnswer<\/span><\/summary>\n

Answer: (b) 21
\nHint:
\nHere p'(x) – p'(1 – x).
\nIntegrating, p (x) = -p (1 – x) + c ………… (1)
\nAt x = 0, p(0) = -p (1) + c
\n\u21d2 1 = -41 + c \u21d2 c = 42.
\nPutting in (1),
\np (x) = -p(1 – x) + 42
\n\u2234 \\(\\int_{0}^{1}\\) p(x) dx = –\\(\\int_{0}^{1}\\) p(1 – x)dx + \\(\\int_{0}^{1}\\) 42 dx

\nAnswer<\/span><\/summary>\n

Answer: (d) (\\(\\frac { 1}{5}\\), 0)
\nHint:
\nHere I4<\/sub> + I6<\/sub> = a tan5<\/sup> x + bx5<\/sup> + c
\n\u21d2 \u222btan4<\/sup>x dx + \u222btan6<\/sup> x dx = a tan5<\/sup> x + bx5<\/sup> + c.
\nDiff. both sides,
\ntan4<\/sup> x + tan6<\/sup> x = 5a tan4<\/sup> x sec\u00b2 x + 5bx4<\/sup>
\n= 5 a tan4<\/sup> x(1 + tan2<\/sup> x) + 5 bx4<\/sup>
\n= 5a tan4<\/sup> x + 5a tan6<\/sup>x + 5bx4<\/sup>.
\nComparing, 1 = 5a and 5b = 0
\n\u21d2 a = \\(\\frac { 1 }{5}\\) and b = 0.
