1. Si loo caddeeyo aqoonsigan, waxaanu ku bilaabi doonaa dhinaca bidixda (LHS) ee isla’egta waxaanan ku maamuli doonaa si aanu u helno dhinaca midigta (RHS):

LHS: (1-sinx)/(1+ sinx)

LHS: (1-sinx)/(1+sinx) * (1-sinx)/(1-sinx)

LHS: (1 – 2sinx + sin²x)/(1 – sin²x)

Tallaabada 2: Isticmaal aqoonsiga sin²x + cos²x = 1 si aad ugu badasho cos²x 1 – sin²x:

LHS: (1 – 2sinx + sin²x)/cos²x

Talaabada 3: Isticmaal aqoonsiga sexx = 1/cosx iyo tanx = six/cosx si aad ugu qorto RHS xaga sexx iyo tanx:

RHS: (sx – tanx)²

RHS: (1/cosx – six/cosx)²

RHS: ((1-sinx)/cosx)²

RHS: (1 – 2sinx + sin²x)/cos²x
