```										$r*b=a*b \\=>c*(r*b)=c*(a*b) \\=>r(c.b)-b(c.r)=a(c.b)-b(c.a) \\=>r(c.b)=a(c.b)-b(c.a) \\=>r(c.b)*a=(a(c.b)-b(c.a))*a \\=>r*a=-b*a(c.a)/c.b \\=>r*a=r*b(c.a)/(c.b)$Arun KumarIIT DelhiAskiitians Faculty

If a,b,c be the unit vectors such that b is not parallal to c and a X(2bXc)=b then the angle that a makes with b and c are respectively where (X represents cross product)

We need to look at only one relation Taking dot product both sides wrt a the LHS will become zero (obviously) hence also now we can expand the given vector triple product as as a.b=0 and...

If a X b= c X d and a X c= b X d then the vectors a-d and b-c are: a)non-collinear b)linearly independent c)perpendicular d)parallal Please explain how to approach these type of quesions

subtracting the two we have hence hence for such a situation to occur the vectors a-d and b-c are parallal

How to find integration of tan3x.tan2x.tanx.? Is there any easy way to solve it

use standard identities first and then reduc this to an easy expression eqn. then integearte it. Use, tan(A+B) = (tanA + tanB)/(1 – tanAtanB) tanAtanB = 1 – (tanA + tanB)/tan(A+B) for tan2x ...
