Question

d/dt
Sec sqrt t
I am not sure which rule I should do.

Answer 1

product rule.

Answer 2

\[\sec (\sqrt{t})?\]
Then chain rule

Answer 3

or is it: \(\sf \color{red}{sec(\theta )\sqrt{t}}\) ?

Answer 4

chain rule, its a composite function. sec(x) is a function and sqrt(x) is a function, together they make a composite function :)

Answer 5

sorry, that should be: \(\sf \color{blue}{sec(t)}\)

Answer 6

chain rule, derivative of the outside multiplied by derivative of the inside.
