Question

what is the derivative of
sec(0.68x)^.5

:)

Answer 1

I hope you mean:
\[\sec \sqrt{0.68x}\]

Answer 2

derivative sec((0.68x)^.5)

Answer 3

if u mean:
\[\sec(0.68x) ^{1/2}\]
answer is:
\[(1/2)(0.68x) ^{1/2} \sec(0.68x) ^{1/2} \tan(0.68x) ^{1/2} \]

Answer 4

use the chain rule of differentiation.
