67. Given, f (x) = (ax2 + sin x) (p +q cos x).

So, f? (x) = (ax2 + sin x) ddx  (p+qcosx)+ (p+qcosx)ddx (ax2+sinx)

= (ax2+sinx) (0+qddxcosx)+ (p+qcosx) (addx (x2)+ddxsinx)

= (ax2+sinx) (q (sinx)+ (p+qcosx) (a·2x+cosx)

= q sin x (ax2 + sin x) + (p + q cos x) (2ax + cos x)

65. Given, f (x) = x4. (5 sin x 3 cos x)

f(x)=x4ddx(5sinx3cosx)+(5sinx3cosx)dx4dx.

=x4[5ddxsinx3·dcosxdx]+[5sinx3cosx]·4x3

As ddxsinx=cosx

and ddxcosx=sinx

Thus,

f(x)=x4[5cosx+3sinx]+[5sinx3cosx]·4x3

=x3[5cosx+3xsinx+20sinx12cosx]

=x3[5xcosx+3xsinx+20sinx12cosx].

64.  Given, f (x) = sin(x+a)cosx

f(x)=cosxddxsin(x+a)sin(x+a)ddxcosxcos2x

Let g?(x) = sin (x + a)

So, g?(x) = limh0g(x+h)g(x)h

= cos (x + a)

And P(x) = cos x

So, P?(x) = limh0p(x+h)p(x)h

Thus, f?(x) = cosx·cos(x+a)sin(x+a)(sinx)cos2x

=cosx·cos(x+a)+sin(x+a)sinxcos2x

=cos(x+ax)cos2x

=cosacos2x

63. Given, f (x) = a+bsinxc+dcosx

f?(x) = (c+dcosx)ddx(bsinx)(a+bsinx)ddx(c+dcosx)(c+dcosx)2

f(x)=(c+dcosx)·b·ddx(sinx)(a+bsinx)·d·ddx(cosx)(c+dcosx)2_____(1)

{Copy (A)}

So, g?(x) = limh0g(x+h)g(x)h

=limh01h[cos(x+h)cosx]

=limh01h[2·sin(x+h+x2)sin(x+hx2)]

=limh01h[2sin(2x+h2)sin(h2)]

=sin(2x+02)×1

= sin x ______ (2)

And p?(x) = limh0p(x+h)p(x)h

=limh0sin(x+h)sinxh

=limh01h2cos(2x+h2)sin(h2)

=limh0cos(2x+h2)×limh0sin(h2)(h2)

= cos x _____ (3)

So, put (2) and (3) in (1) we get,

f(x)=(c+dcosx)(b·cosx)(a+bsinx)(d·sinx)(c+dcosx)2

=beccosx+bdcos2x+adsinx+bdsin2x(c+dcosx)2

=bccosx+adsinx+bd(cos2x+sin2x)(c+dcosx)2

=bccosx+adsinx+bd(c+dcosx)2

62. Given, f (x) =sinnx

By chain rule,

f? (x) = n (sin x)n-1 ddh sin x

Let (gx) = sinx

So, g? (x) limh0g (x+h)g (x)h

=limh0sin (x+h)sinxh

=limh02hcos (2a+h2)sin (h2)

=limh0cos (2x+h2)×limh0sin (h2)h2

cos (2x+0)2×1

= cos x.

So, f? (x) = n (sin x)n-1 cos x.

If you are in general category then it is possible to get SSN but don't be sure on this because this rank is on the edge of final cutoff but if you are from categories like BC then the cutoffs are more high than the general category one. If we talk about previous cutoffs then it seems possible to get admission with this cut off but if you are in other category then it's not possible

61. Given, f (x) = secx1secx+1

=1cosx11cosx+1

=1cosx1+cosx

So, f?(x) = (1+cosx)ddx(1cosx)(1cosx)ddx(1+cosx)(1+cosx)2

=(1+cosx)(1)ddx(cosx)(1cosx)ddx(cosx)(1+cosx)2

Let g(x) = cos x.

So, g?(x) =limh0g(x+h)g(x)h

=limh0cos(x+h)cosxh

=limh02hsin(x+h+x2)sin(x+hx2)

=limh02hsin(2x+h2)sin(h2)

=limh0sin(2x+h2)×limh0sinh2h2

=sin(2x+02)×1

= -sin x.

So, f?(x) (1+cosx)(1)(sinx)(1cosx)(sinx)(1+cosx)2

=sinx+cosxsinx+sinxsinxcosx(1+cosx)2

=2sinx(1+cosx)2

=2sinx(1+1secx)2=2sinx×sec2x(secx+1)2=2secx·sinx(sinx+1)2·cosx.

60. Given, f (x) = sinx+cosxsinxcosx

So, f?(x) = sinxcosxddx(sinx+cosx)(sinx+cos2)ddx(sinxcosx)(sinxcosx)2

Let g(x) = cos x and p(x) = sin x.

{from so g’(x) A ) (upto equation 3)

Let g(x) = cos2 and p(x) = sin x.

So, g?(x) = limh0g(x+h)g(x)h

=limh01h[cos(x+h)cosx]

=limh01h[2·sin(x+h+x2)sin(x+hx2)]

=limh01h[2sin(2x+h2)sin(h2)]

=sin(2x+02)×1

= -sin x ______ (2)

And p?(x) = limh0p(x+h)p(x)h

=limh01h2cos(2x+h2)sin(h2)

=limh0cos(2x+h2)×limh0sin(h2)(h2)

= cos x _____ (3)

Putting (2) and (3) in (1) we get,

f(x)=(sinxcosx)[cosxsinx](csinx+cosx)[cosx+sinx](sinxcosx)2

=(sinxcosx)2(sinx+cosx)2(sinxcosx)2

=(sin2x+cos2x)+2sinxcosx(sin2x+cos2x)2sinxcosx(sinxcosx)2
