Engineering Mechanics
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.)

y = x. tanα + (gx²/2u² cos²α)

y = (gx²/2u² cos²α) - x. tanα

y = x. tanα - (gx²/2u² cos²α)

y = (gx²/2u² cos²α) + x. tanα

y = x. tanα + (gx²/2u² cos²α)

y = (gx²/2u² cos²α) - x. tanα

y = x. tanα - (gx²/2u² cos²α)

y = (gx²/2u² cos²α) + x. tanα
