SUMMARY

The discussion focuses on solving the derivative of the function y = x^tan(x). To differentiate this function, one should rewrite it as y = exp(tan(x) * ln(x)) and then apply the chain rule. An alternative method involves taking the natural logarithm of both sides, simplifying using properties of logarithms, and differentiating. The key takeaway is to remember that the derivative of ln(y) is (y'/y).

PREREQUISITES
  • Understanding of basic calculus concepts, particularly differentiation
  • Familiarity with the chain rule and logarithmic differentiation
  • Knowledge of exponential functions and their properties
  • Proficiency in manipulating functions involving natural logarithms
NEXT STEPS
  • Study the chain rule in depth to enhance differentiation skills
  • Learn about logarithmic differentiation techniques for complex functions
  • Explore the properties of exponential functions and their derivatives
  • Practice solving derivatives of functions in the form y = f(x)^[g(x)]
USEFUL FOR

Students preparing for calculus exams, educators teaching differentiation techniques, and anyone looking to strengthen their understanding of advanced derivative concepts.

Having trouble understanding how to solve the derivative of y=x^tanx?

Like the question says. Can someone help me please? I have an exam tomorrow and having trouble solving these.

assuming you want dy/dx...

in general for a function like y(x) = f(x)^[g(x)], you write y(x) = exp(g(x)*ln(f(x)) then differentiate with respect to x.
 
Another way of viewing it is to take the natural logarithm of both sides, and then use the properties of ln to simplify things on the right hand side. Then take the derivative of both sides and solve for y'. This is the same thing that fluxions said, just a slightly different approach that I think is a little easier to work with since you don't have the exponential in the way. Just remember that (ln(y))'=y'/y.
