i need some serious help with limits in precalc.
here are a few questions that i really do not understand.
1. Evaluate: lim (3x^32x^2+5) x> 1
2. Evaluate: lim [ln(4x+1) x>2
3. Evaluate: lim[cos(pi x/3)] x>2
4. Evaluate: lim x^2+x6/x^29 x> 3
5. Evaluate: lim x^25x+4/x^22x8 x>4
6. For the function x^2+2x+4 find lim f(h+4)f(4)/h h> 0
