Question

Second Derivative of tan(x^2)??

Answer 1

use the chain rule to find first derivative
can u do that?

Answer 2

actually you don't need the chain rule to solve this derivative, the basic differentiation of tan(x)
\[f(x) = \tan (x) \rightarrow f \prime (x) = \sec ^{2} (x) \times (1)\]
where (1) is the derivative of x.
solve this derivative on this basis

Answer 3

r u there lucy?

Answer 4

what is the answer? that derivative of tan (x^2)

Answer 5

I thought we would do chain rule... the first derivative is 2xsec^2(x^2)

Answer 6

Now use the product rule

Answer 7

right
