-_-. As for leveling up, the exp caps at about 70,000 after 15 minutes. So you can't leave your game on for a whole day in hopes of getting a million exp. xD Just let the MC smack these guys around for a good 20 minutes and he'll level up 2-3 times. It's guaranteed the best way to level up in the game.
tanÂ·gent. n. 1. Mathematics. a. A line, curve, or surface meeting another line, curve, or surface at a common point and sharing a common tangent line or tangent plane at that point.
In right triangle trigonometry (for acute angles only), the tangent is defined as the ratio of the opposite side to the adjacent side. The unit circle definition is tan(theta)=y/x or tan(theta)=sin(theta)/cos(theta). The tangent function is negative whenever sine or cosine, but not both, are negative: the second and fourth quadrants. Tangent is also equal to the slope of the terminal side.
