Hello po, nagtanung na po ako dito dati. Highest po ako maraming salamat sainyo.

May tanong po ulit ako:

1. tan²x-1/tan²x+1 =1-2cosx
(work on left)

2. (1+sinx)/cosx = cosx/(1-sinx)
(work on right)

Ipoprove lang po na equal sila. Maraming salamat po.
 
lagyan mo na ng "( )" boss if magkasama ba sila. like sa number to parang ganito yata yan (1+sinx)/cosx = cosx(1-sinx) or ganito ba yan 1+(sinx/cosx) = cosx(1-sinx) para di malito yung mag solve.
