θ = sin^(−1)  (−(3/5))+k.360°  θ = 180°−sin^(−1) ((3/5))+k.360°  where sin^(−1) (−(3/5))= −0.643501
θ=sin1(35)+k.360°θ=180°sin1(35)+k.360°wheresin1(35)=0.643501

sinθ=((−3)/5)=−0.6=−sin37^o   sinθ=sin(180^o +37^o )=sin217^o   sinθ=sin(360^o −37^o )=sin323^o
sinθ=35=0.6=sin37osinθ=sin(180o+37o)=sin217osinθ=sin(360o37o)=sin323o
