First derivative of
√{cosec2x).show with full step.​

Step-by-step explanation:

we are given a derivative

and said to figure out the first derivative

to do so

recall chain rule:

so we get

rewrite the derivative using the chain rule:

use square root derivative rule to simplify:

now we need to again use chain rule composite function derivative to simplify

where we'll take a new function n so we won't mess up two g's and we'll take 2x as n

use composite function derivative to simplify:

use derivative formula to simplify derivatives:

substitute the value of n:

substitute the value of g:

now we need our trigonometric skills to simplify

rewrite cot and csc:

simplify multiplication:

simplify multiplication:

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
