If α is the angle between the polar ray and the tangent at the point of commencement of a lemniscate curve, the equation of the curve, is
l = ksin α
l = ksin 2α
l = ksin 3α
l = ktan 2α
l = kcos 2α

Pick up the correct statement from the following :
If the slope of the curve of a mass diagram in the direction of increasing abscissa is downward, it indicates an embankment
The vertical distance between a maximum ordinate and the next forward maximum ordinate represents the whole volume of the embankment
The vertical distance between a minimum ordinate and the next forward maximum ordinate represents the whole volume of a cutting
The area enclosed by a loop of the curve and balancing line, measures the haul in that direction.
all the above.
