[sin2B=2sin B" is true when "B" is "],[" equal to "^(*)]

sin 2B = 2 sin B is true when B is equal to

Sin 2A= 2 sin A is true when A equals to

If sin2B=2sin B then angle B equal to

If A and B are acute positive angles satisfying the equations 3sin^(2)A+2sin^(2)B=1 and 3sin2A-2sin 2B=0 , then A+2B is equal to

(sin^(2)A-sin^(2)B)/(sin A cos A-sin B cos B) is equal to (a) sin A cos A-sin B cos Btan(A-B)(b)tan(A+B)cot(A-B)(d)cot(A+B)

sin2A=2sin A is true when A=0o(b)300 (c) 45o(d)60o

If A and B are acute positive angles satisfying the equations 3 sin^(2)A+2sin^(2) B=1 and 3 sin2A-2 sin 2B=0 , then A+2B is equal to

If A+B=(pi)/(2) and sin A+sin B=1 then sin2A is equal to

(sin ^(2) A - sin ^(2) B)/( sin A cos A - sin B cos B) is equal to
