Use the range formula for projectile motion:

[ R = \frac{u^2 \sin(2\theta)}{g} ]

where ( R ) is the range, ( u ) is the initial speed, ( \theta ) is the launch angle, and ( g ) is the acceleration due to gravity.

Given: ( u = 1 ) m/s ( \theta = \frac{\pi}{8} ) ( g = 9.8 ) m/s²

Find the range (( R )).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
