Differentiate the following functions:
1) 3 cot x + 6(1-2x)^5/3
2) (1-2 tan x)(5+4 sin x)

Dear student,Assuming the questions to be:1. y=3cot x+61-2x53dydx=3(-cosec2' x)+6×53×1-2x23×(-2)=-3cosec2 x-201-2x232. y=1-2tan x(5+4sin x)dydx=(1-2tan x)×4cos x+(5+4sin x)(-2sec2 x)=4cos x(1-2tan x)-2sec2 x(5+4sin x)Regards
