Have you worked on these questions. Please post the effort made.
a) as the highest powers in both the numerator and denominator are the same when expanded, the limit is just the coefficients of the highest powers in the numerator and denominator.
So, 2/10 which simplifies to 1/5.
b) as the numerator's highest power is greater than the denominator's highest power - the limit does not exist.
c) as the numerator's power is lower than the denominator's power, the limit is equal to 0.
??
Is this correct?
Please get back to me!
You can verify by dividing the numerator and denominator by the highest power of the variable.
Q 1. it is x^3. On dividing the numerator and the denominator by x^3 we get [2 - 2/x^2 ] / [ 5 - 4/x] the limit of this as x approaches infinity is 2/5
Similarly you can find the limits of other questions.
