Question

Find differentiative coeffiecient of tan x with respect to cos x

Answer 1

d(tanx)/d(cosx)=?
let tanx=u
and cosx=v
we have to find :
du/dv=?
here,u=tanx
differentiate with respect to x
du/dx=sec²x -(1)
here,v=cosx
differentiate with respect to x
dv/dx=-sinx -(2)
divide : (1)÷(2)
du/dx= -sec²x/sinx
