If the direction ratios of a line are `1 + lambda, 1- lambda, 2,`
and it makes an angle of `60^(@)` with the y-axis then
`lambda` is

If the direction ratios of a line are 1+lambda, 2-lambda, 4 and if it makes an angle of 60^(@) with the y- axis, then the sum of the values of lambda is

If the direction ratios of two lines are (1, lambda, 2) and (lambda, lambda + 1, lambda) and the angle between the lines is 90^(@) then the modulus of sum of all values of lambda is ________

The direction ratios of two parallel lines are 4,-3,-1 and lambda+mu,1+mu,2. The value of the pair (lambda,mu) is

The point (lambda+1,1),(2 lambda+1,3) and (2 lambda+2,2 lambda) are collinear,then the value of lambda can be

If the points A(lambda, 2lambda), B(3lambda,3lambda) and C(3,1) are collinear, then lambda=

If the area (in sq.units) bounded by the parabola y^(2)=4 lambda x and the line y=lambda x,lambda>0, is (1)/(9), then lambda is equal to:

Portion of asymptote of hyperbola x^2/a^2-y^2/b^2 = 1 (between centre and the tangent at vertex) in the first quadrant is cut by the line y + lambda(x-a)=0 (lambda is a parameter) then (A) lambda in R (B) lambda in (0,oo) (C) lambda in (-oo,0) (D) lambda in R-{0}
