Tap for more steps Step 16. $$ tan^2x=(tan x)^2 $$ differentiate using the chain rule given $$ y=f(g(x)) $$ then $$ \frac{dy}{dx}=f'(g(x)) \times g' (x) \leftarrow $$ chain rule $$ y=(tanx)^ 2$$ $$ \Rightarrow \frac{dy}{dx}=2\ tanx \times \frac{d}{dx}(tanx)$$ =$$ 2\ tanx\ sec^2 x$$ Was this answer helpful? 18. Related This section explains how to differentiate the six basic trigonometric functions: sine, cosine, tangent, cotangent, secant, and cosecant. To get. Q1. C. Simplify. And factoring the difference of squares on the left: #(secx-tanx)(sec x +tan x)# (The is the same bit of algebra we use to rationalize fractions involving #sqrta - b#. By the Sum Rule, the derivative of with respect to is . Step 9. The derivative of tan 2x is given by 2 sec 2 (2x) which can be calculated using different methods such as chain rule, the first principle of derivatives, and quotient rule. sourabh_jain.
