    lets first look at : (secx + cscx)(sinx+cosx)

    and you should know that secx = 1/cosx and cscx = 1/sinx

    lets do it together since i got something else. (secx + cscx)(sinx+cosx) = secxsinx + secxcosx + cscxsinx +cscxcosx = tanx + 1 + 1 + cotx

    so (secx + cscx)(sinx+cosx) = 2 + cotx + tanx now lets add it to the rest : (secx + cscx)(sinx+cosx) - 2 - cotx = 2 + cotx + tanx -2 -2 - cotx = tanx
