√3(sina+sinb)=cosb-cosa,a.b均为锐角,a+b=√3(sina+sinb)=cosb-cosa,a.b均为锐角,a+b=√3(sina+sinb)=cosb-cosa,a.b均

√3(sina+sinb)=cosb-cosa,a.b均为锐角,a+b=
√3(sina+sinb)=cosb-cosa,a.b均为锐角,a+b=

√3(sina+sinb)=cosb-cosa,a.b均为锐角,a+b=
√3(sina+sinb)=cosb-cosa 可化为√3sina+√3sinb=cosb-cosa
√3sina+cosa=cosb-√3sinb
2sin(a+π/6)=2cos(b-π/3)
sin(a+π/6) =sin(π/2 - b +π/3)
应为a,b 都为锐角,所以 a+π/6 =π/2 - b +π/3所以 a+b= 2π/3
