**advanced funtions**

when u have an even power, the value of y will always be positive, when u have an odd power, the value of y will be negative for x < 0 The higher the power the steeper the slope will be the graphs of x^n for even and odd n's are the same except that they are inverted ...

1st you find the vertical component of its speed which = (120)sin(60)=103.92 m/s Gravity's pull will decrease its vertical speed by G (=9.8 m/s^2) Therefore the vertical velocity of the projectile = 103.92 - (9.8)*t (whee t is time in seconds) It will reach maximum height ...
