Number 1: Lim x->oo X√3/x^2 Solution: Divide the numerator and denominator by the highest power of x, in this case x^2 =X√3/x^2/ x^2/x^2 =√3/x / 1 Remember as X tends to infinity, C/x tends to zero, where C is a constant. = 0/1 =0. |

Follow the same procedure for question 2 and 3. If done correctly you should get 2 for question 2, and 0 for question 3. |

Question 4 is trivial, although it'll be long: just apply the first principle. x= X + ∆x; y = Y + ∆y. Substitute those for X and Y respectively so the question reads: Y + ∆y = (∆x + x)^4 + 5(x + ∆x)^3 -4(x + ∆x)^2 +7(x + ∆x) -2 Expand this and make ∆y the subject if the formula (don't forget to substitute the original function for Y) Divide through by ∆x, then limit ∆x to 0. That's all to it. I trust you can take it from here. The answer should be: 4x^3 +15x^2 -8x + 7 Hope this helps. Cheers. PS: Try out different practice questions so you can master it. 1 Like 1 Share |
