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
