sina+cosa=1/5,0
sina+cosa=1/5,0
sina+cosa=1/5,0
由sina+cosa=1/5,和(sina)^2+(cosa)^2=1
再加上条件0
sina+cosa=1/5,0
已知sina+cosa=1/5,0
设sinA+cosA=1/5,0
sina+cosa=1/5(0
sina+cosa=-1/5,0
知sina+cosa=1/5,0
已知sina+cosa=1/5,0
已知sina+cosa=-1/5,0
sina+cosa=-1/5,0
sina+cosa=1/5(0
已知sina+cosa=1/5,0
已知sina+cosa=1/5(0
已知sina+cosa=-1/5(0
已知3sina+cosa=0求(1)(3cosa+5sina)/sina-cosa(2)sina+2sinacosa-3cosa
已知,5sina+2cosa=0,求sina*cosa
已知12sina+5cosa=0,求sina,cosa
已知sina+cosa=1/5,则sina*cosa=
已知sina+cosa=1/5求sinacosa,sina-cosa
