#d/dx(sin^-1 csc (4x))=4*sec 4x*sqrt(1-csc^2 4x)#

We use the formula

#d/dx(sin^-1 u)=(1/sqrt(1-u^2))du#

#d/dx(sin^-1 csc (4x))=(1/sqrt(1-(csc 4x)^2))d/dx(csc 4x)#

#d/dx(sin^-1 csc (4x))=(1/sqrt(1-csc^2 4x))*(-csc 4x*cot 4x)*d/dx(4x)#

#d/dx(sin^-1 csc (4x))=((-csc 4x*cot 4x)/sqrt(1-csc^2 4x))*(4)#

#d/dx(sin^-1 csc (4x))=((-4*csc 4x*cot 4x)/sqrt(1-csc^2 4x))*(sqrt(1-csc^2 4x)/(sqrt(1-csc^2 4x)))#

#d/dx(sin^-1 csc (4x))=((-4*csc 4x*cot 4x*sqrt(1-csc^2 4x))/(-cot^2 4x))#

#d/dx(sin^-1 csc (4x))=4*sec 4x*sqrt(1-csc^2 4x)#

God bless....I hope the explanation is useful.
