I need some help desparately. My teacher allowed us to bring cards to the final with some equations, only my dumbass teacher lost it so I'm screwed atm. I need to know the essential equations for projectile motion (there's 6 I believe) and the ones for: - Torque - Simple Harmonic Motion - Waves - Fluid Statics - Lenses/Mirros and Diffraction - Magnetism - Waves - Gravitation Any help would be GREATLY appreciated. I don't have much to offer except a lifetime worth of thanks. Please help as I am in a very desparate situation at the moment. Cheers.
