In this lesson, we'll see how to differentiate logarithmic and exponential functions. Tips and Troubleshooting Not getting our emails? Solltest du dein Konto immer noch nicht finden können, kann dir möglicherweise ein Freund bzw. The best thing to do in this case is to create a new account.

Therefore, the natural logarithm of x is defined as the inverse of the natural exponential function: $$\large ln(e^x)=e^{ln(x)}=x$$ In general, the logarithm to base b, written $$\log_b x$$, is the inverse Sometimes we make mistakes though, so if you think we shouldn’t have suspended your account, get in touch with us.   Make sure to check out our content policies to see it makes things look strange. This we can do by the chain rule: $$f(x)=e^x$$; $$g(x)=x*ln4$$ $$\frac{d}{dx}(f(g(x)))=ln4*e^{x*ln4}=ln4*4^x$$ Example 2 Problem: Find $$\frac{d}{dx}(\log_2x)$$ Solution: Again by the base change formula we know that $$\large \log_2x=\frac{lnx}{ln2}$$ So, just take the http://www.purplemath.com/modules/logs.htm

Just use this formula: "x goes up, a goes down" Or another way to think of it is that logb a is like a "conversion factor" (same formula as above): loga Vielleicht interessierst du dich dafür, wie du dich vor schadhafter Software schützen kannst, die eine potenzielle Gefährdung deines Kontos darstellt.Vollständigen Artikel anzeigen · Artikel teilenWie hilfreich war diese Antwort?Ich bin mir Neutralize data Planning a course: lecture-by-lecture or topic-by-topic?
