All you need to know are a few extra things like these
d/dx sin x = cos x
d/dx cos x = - sin x (it’s a negative sign, important to know the sign)
d/dx tan x = sec^2 x
d/dx e^x = e^x
d/dx ln x = 1/x
Chain rule, product rule, quotient rule, maxima minima, rates of change and so on continue to apply.
Also, you need to continue to be proficient in trigo, especially during maxima minima when equations reduce to trigo.

Done. Chain rule, product rule and quotient rule continue to apply. I will cut short the steps from now on.

How to apply the rule
It’s the same which you have been doing the previous time, except that now trigo functions are involved.
