If x+1/x=2 then x^(12)-1/x^(12)=

Let I_1=int_0^1e^(x^2)dx and I_2=int_0^(12)2^(x^2)e^(x^2)dx then the value of I_1 +I_2 is equal to

Let V_(1)=3ax^(2)i-2(x-1)j and V_(2)=b(x-1)i+x^(2)j where,ab<0. The vector V_(1) and V_(2) are linearly dependent for

If sum_(i=1)^(10)(x_(i)-15)=12 and sum_(i=1)^(10)(x-15)^(2)=18 then the S.D.of observation x_(1),x_(2),x_(3),....x_(10) is:
