#y^2=sin(x-1)#

#=>y=sqrt(sin(x-1))#

#=>dy/dx=d/dx((sin(x-1))^(1/2))=1/2*(sin(x-1))^(1/2-1)*d/dx(sin(x-1)) #

#=>dy/dx=1/(2sqrt(sin(x-1))) * cos(x-1)*d/dx(x-1)#

#=>dy/dx = cos(x-1)/(2sqrt(sin(x-1)))#

#(dy)/(dx)=cos(x-1)/(2sqrt(sin(x-1))#

#d/(dx)(y^2)=d/(dx)(sin(x-1)#

#=>2y(dy)/(dx)=cos(x-1)#

#(dy)/(dx)=1/(2y)(cos(x-1)#

#(dy)/(dx)=cos(x-1)/(2sqrt(sin(x-1))#
