## Limit of (x^n-a^n)/(x-a) as x approaches a: Formula, Proof

The limit of (x^n-a^n)/(x-a) as x approaches a is equal to nan-1. This limit is denoted by limx→a (xn-an)/(x-a), so the limit formula of (xn-an)/(x-a) when x tends to a is given as follows. limx→a (xn-an)/(x-a) = n⋅an-1 Lets prove this limit formula. Proof of limx→a (xn-an)/(x-a) To prove limx→a (xn-an)/(x-a) = n⋅an-1 we will consider three different cases … Read more

## Limit of (x^n-1)/(x-1) as x approaches 1

The limit of (x^n-1)/(x-1) as x approaches 1 is equal to n, that is, limx→1 (xn-1)/(x-1) = n. This follows from the formula limx→a (xn-an)/(x-a) = n⋅an-1 Put a=1, so we get that limx→1 $\dfrac{x^n-1}{x-1}$ = n. Let us now prove this limit formula. What is the Limit of (x^n-1)/(x-1) Answer: limx→1 (xn-1)/(x-1) is equal … Read more

## Limit of (1+1/x)^x as x approaches Infinity | Lim x→∞ (1+1/x)^x

The limit of (1+1/x)^x as x approaches infinity is equal to e. Here we will discuss Lim x→∞ (1+(1/x))^x formula with proof. Note that Limx → ∞ (1+$\frac{1}{x}$)x = e. Limx→∞ (1+(1/x))x Formula with Proof The formula of limx→∞ (1+(1/x))x is given by limx → ∞ (1+(1/x))x =e. Explanation: Let y = limx→∞ (1+$\frac{1}{x}$)x. So … Read more

## Limit of cosx/x as x approaches 0 | Lim x→0 cosx/x

The limit of cosx/x as x approaches 0 does NOT exist. That is, limx→0 (cos x)/x is undefined. $\lim\limits_{x \to 0} \dfrac{\cos x}{x}$ = NOT exist. Let us now show that the limit of (cos x)/x when x tends to 0 does not exist. Limx→0 (cos x)/x Question: What is the limit of cosx/x when … Read more

## Limit of cosx/x as x approaches infinity | Lim x→∞ cosx/x

The limit of cosx/x as x approaches infinity is equal to 0. The formula of limx→∞ (cos x)/x is given below: $\lim\limits_{x \to \infty} \dfrac{\cos x}{x}=0$. Here we find the limit of (cos x)/x when x tends to infinity. Limx→∞ (cos x)/x = 0 Proof Question: What is the limit of cosx/x when x tends … Read more
