- Homework Statement
- Show that the range of the projectile is the same for two different projection angles --- a pair that add up to 90 degrees.

- Relevant Equations
- theta1 +theta2 = 90

v^2 * sin(2theta1)/g = v^2 *sin(2theta2)/g

theta1 = 90- theta2

I substituted that into v^2*sin(2theta1)/g

So I get

v^2*sin(180-2theta2)/g

Now I'm stuck. What do I do next?
