Find dy/dx for y = x^lnx Here is the work I have done, however the answer has a "2" in the numerator, I don't know what I did wrong: http://img820.imageshack.us/img820/7229/deriv.png Answer is (2x^lnx)(lnx)/x

Determine the limit graphically lim x --> 0 ( ( 2 + x )^3 - 8 ) ÷ x and lim x --> 0 ( sin x ) ÷ ( 2x^2 - x ) The answers are 12 and -1.

Determine the limit graphically: lim f(x) exists x->0 ( 5x^3 + 8x^2 ) ÷ ( 3x^4 - 16x^2) The answer is (-1/2)

A projectile is sent off with an initial speed of 60.0 m/s and an angle of 30.0 degrees above the horizontal. The projectile lands on a hillside 4 seconds later. Ignore air friction. What is the projectile's velocity at the highest point of its trajectory? What is the straight-line distance...
