If l_1=int_e^(e^2) dx/logx and l_2=int_1^2 e^x/xdx , then (A) l_1=2l_2 (B) l_1+l_2=0 (C) 2l_1=l_2 (D) l_1=l_2
If L_(1)&L_(2) are the lengths of the segments of any focal chord of the parabola y^(2)=x, then (a) (1)/(L_(1))+(1)/(L_(2))=2( b) (1)/(L_(1))+(1)/(L_(2))=(1)/(2)(c)(1)/(L_(1))+(1)/(L_(2))=4(d)(1)/(L_(1))+(1)/(L_(2))=(1)/(4)
Value of [(x^l)^(I - I/l)]^(1/(l - 1)) is:
Let L be the set of all straight lines in plane. l_(1) and l_(2) are two lines in the set. R_(1), R_(2) and R_(3) are defined relations. (i) l_(1)R_(1)l_(2) : l_(1) is parallel to l_(2) (ii) l_(1)R_(2)l_(2) : l_(1) is perpendicular to l_(2) (iii) l_(1) R_(3)l_(2) : l_(1) intersects l_(2) Then which of the following is true ?
