14. If A=60 and B=30, verify that sin(A+B) = sinAcosB+cosAsinB
14. If A = 60 and B = 30 verify that: (i) sin(A + B) = sin Acos B + cos A sin B
14. If A = 60 deg and B = 30 verify that: (ii)cos(A + B) = cos Acos B - sin Asin B
if A=60 and B = 30 verify that sin(A+B) =SinAcosB +cosAsinB
15 If A = 60 and B = 30 verify that: (ii) cos(A - B) = cosAcos B + sinAsinB
