The Cartesian equation of trajectory is (where u = Velocity of projection, α = Angle of projection, and x, y = Co-ordinates of any point on the trajectory after t seconds.)$?

A. y = (gx²/2u² cos²α) + x. tanα
B. y = (gx²/2u² cos²α) - x. tanα
C. y = x. tanα - (gx²/2u² cos²α)
D. y = x. tanα + (gx²/2u² cos²α)
Answer» D. y = x. tan≈í¬± + (gx¬¨‚â§/2u¬¨‚â§ cos¬¨‚â§≈í¬±)
