Direction Cosines And Direction Ratios Of A Line

The direction cosines to two lines at right angles are (1,2,3) and (-2,1/2,1/3) then the direction cosine prependicular to both the given lines are

The equation of a line are 5x-3 =15y+7=3-10z write the direction cosines of the line

If 1/2,1/3,n are direction cosines of a line, then the value of n is

Let alpha be the angle between the lines whose direction cosines satisfy the equation l+m-n=0 and l^2+m^2-n^2=0 then value of (Sinalpha)^4+(Cosalpha)^4 is

The direction cosines l, m and n of two lines are connected by the relations l+m+n=0 and lm=0 , then the angle between the lines is

If the direction ratios of a line are (-18,12,-4), then direction cosines of a line are
