Question
Solve the given problems by finding the appropriate derivative.Find the equation of the line tangent to the curve of $y=\tan ^{-1} 2 x$ where $x=1$
Step 1
The derivative of $\tan ^{-1} x$ is $\frac{1}{1+x^2}$, so the derivative of $\tan ^{-1} 2x$ is $\frac{2}{1+(2x)^2}$ by the chain rule. Show more…
