csc xcot x cot xcsc x tan xcsc x Solutioncscxcotxcotxcscx

*csc x/cot x - cot x/csc x = tan x/csc x

Solution

(cscx/cotx)-(cotx/cscx)

=(cscxcscx -cotxcotx)/(cotx cscx)

=(csc2x -cot2x)/(cotx cscx)

csc2x -cot2x=1 is an identity

=1/(cotx cscx)

=(1/cotx) /cscx

write 1/cotx as tanx

=tanx /cscx

therefore (cscx/cotx)-(cotx/cscx)= tanx /cscx

 *csc x/cot x - cot x/csc x = tan x/csc x Solution(cscx/cotx)-(cotx/cscx) =(cscxcscx -cotxcotx)/(cotx cscx) =(csc2x -cot2x)/(cotx cscx) csc2x -cot2x=1 is an ide
