Projectile on an Incline Calculator

Calculate key parameters for a projectile launched on an incline (with the projectile moving upward relative to the plane).
The equations used are:
Time of Flight: \[ t = \frac{2\,v_0\,\sin\left(\theta-\phi\right)}{g\,\cos\phi} \]
Range along the incline: \[ R = \frac{2\,v_0^2\,\cos\theta\,\sin\left(\theta-\phi\right)}{g\,\cos^2\phi} \]
Maximum height above the incline: \[ h = \frac{v_0^2\,\sin^2\left(\theta-\phi\right)}{2\,g\,\cos\phi} \]
*Ensure that the launch angle (θ) is greater than the incline angle (φ).

* Enter the initial velocity (m/s), launch angle (°), incline angle (°), and gravitational acceleration (m/s²).
