Answer:
The power developed by the 1st crane is twice the power developed by the 2nd crane.
Step-by-step explanation:
According to the question,
work done by both of the cranes are the same. Let it be W.
Then power developed by the first crane,
= unit -----------------(1)
and, the power developed by the 2nd crane,
= unit ------------------(2)
So, we get that,
So, the power developed by the 1st crane is twice the power developed by the 2nd crane.
Answer:

Step-by-step explanation:
here's your solution
Csc x · sec x - tan x =
= 1 / sin x · 1 / cos x - sin x / cos x =
= 1 / sinx cos x - sin² x / sin x cos x =
= ( 1 - sin² x ) / (sin x cos x) =
= cos² x / ( sin x cos x ) =
= cos x / sin x = cot x
