cscx-sinx=(cosx)(cotx) 1/sinx-sinx=(cosx)(cosx/sinx)(1/sinx)-(sin^2x/sinx)=cos^2x/sinx cos^2x/sinx=cos^2x/sinx Therefore LS=RSYou have to remember some trig identities when answering these questions....
Sorry. I can't solve that because it is not an equation. An equation has an equals sign, and a solution is a set of assignments to the variables of the equation that would make it true. For example:...
