Evaluating Limits Using Logarithms |

The exercises are composed of several steps. An exercise goes on, even if a false reply has been given at the precedent step.

The good answers are provided after each step, limits of logarithmic functions enable further evaluations. If you're taking a limit to a point that's not in their domain, there's a good chance that we're not going to have a limit. So here, there is no limit.

And the way to do that is that pi over two is not in tangent of x's domain.

If you limits of logarithmic functions to graph tan of x, you would see a vertical asymptote at pi over two. Let's do one more of these.

So let's say the limit as x approaches pi of cotangent of x, pause the video and see if you can figure out what that's going to be.

Well, one way to think about it, cotangent of x is one over tangent of x, it's cosine of x over sine of x. This is a limit as x approaches pi of this.

Limits of Logarithmic Functions

And is pi in the domain of cotangent of x? Referring to the opening example given in 1we see limits of logarithmic functions when applying the Limit of Composition Functions theorem, and In addition, by using differentiation or by merely looking at the graph of g, it becomes clear that and this means condition 3 in the theorem holds.

Although unconventional, we assume condition 1 limits of logarithmic functions holds for this case-it is this limit we are seeking after all. Finally condition 2 is valid, since necessarily exists.

L'Hospital's Rule Suppose the functions f and g satisfy the following conditions. Differentiability implies continuity We see that if a function is differentiable at a point, then it must be continuous at that point.

Basic rules of differentiation We derive the constant rule, power rule, and sum rule. The derivative of the natural exponential function We derive the derivative of the natural exponential function.

The derivative of sine We derive the derivative of sine. Product rule and quotient rule Derivatives of products are tricky Two young mathematicians discuss derivatives limits of logarithmic functions products and products of derivatives.

The Product rule and quotient rule Here we compute derivatives of products and quotients limits of logarithmic functions functions Chain rule Two young mathematicians discuss the chain rule.

The chain rule Here we compute derivatives of compositions of functions Derivatives of trigonometric functions We use the chain rule to unleash the derivatives of the trigonometric functions. Higher order derivatives and graphs Rates of rates Two young mathematicians look at graph of a function, its first derivative, and its second derivative.

Higher order derivatives and graphs Here we make a connection between a graph of a function and its derivative and higher order derivatives. Forwe get Example 5 Evaluate limits of logarithmic functions of the following limits.

Logarithms and Exponential Functions

Example 6 Evaluate each of the following limits. The real issue is whether or not the argument of the limits of logarithmic functions will be negative or not. Therefore, not only does the argument go to zero, it goes to zero from the right.
