 Q.1. Find Limitx---->0 8/x8[1-cosx2/2 -cosx2/4 +cosx2/2 .cosx2/4]

7 years ago


Answers : (1)





=Limitx--->032/(4282) [(sinx2/4)/(x2/4)]2[(sinx2/8)/(x2/8)]2  =1/32*Limitx---->0[(sinx2/4)/(x2/4)]2[(sinx2/8)/(x2/8)]2 


Here i used following formulas:


Limity--->0siny/y = 1 [replace y by x2/4 and x2/8 to get a new result which is used in solving above problem...]

Apply L-Hospital. it would become = > (0 + sinx root(cos2x) - cosx * 0.5*1/root(cos2x) * sin2x * 2)/e^(x^2) * 2x apply again . means again apply L-Hospital. if 0/0 indeterminat forms.

what is meant by vector triple product?????????????????????????????
If the scalar triple point is equal to zero, then the three vectors a, b, and c are coplanar. multiplication of three vectors also called the vector three product.
