I got 60% for bio. 51% for eco For bio i crammed in the end, eco i studied hard for half yearly, and crammed in the end I crammed more in bio than eco - by rote learning Which should i drop, which is harder in HSC, can i get through bio and get band 5/6 by rote learning? I am willing to go...

Can someone PLEASE explain to me the difference between: \Delta > 0 and \Delta \geq 0 BEFORE u say anything, i know that when \Delta = 0 there is exactly 1 root

A ball is projected from a point on the ground, distance a from the foot of a vertical wall of height b. The ball is projected at an elevation \theta with speed V. a) Find how high above the wall the ball passes it. b) If the ball just cleans the wall, prove the greatest height reached is...

--------------- 1. A target is hung on a wall at height h metres. A small cannon which fires a slimy lead slug, is located on the floow, d metres from the rigid wall. The muzzle velocity, V, of the cannon is adjustable. The cannon is aimed at the bulls eyes on the target at an angle of...
