If cot (alpha + beta) = 0 , then sin (alpha + 2 beta) is equal to

If cot (alpha + beta) = 0 , then sin (alpha + 2 beta) is equal to

IF cot ( alpha + beta ) =0 then sin ( alpha + 2 beta ) is equal to

If cot ( alpha + beta) = 0 then sin ( alpha + 2 beta) =

If cot(alpha+beta)=0, then sin(alpha+2 beta) can be (a)-sin alpha(b)sin beta(c)cos alpha(d)cos beta

If cot(alpha+beta)=0, then sin(alpha+2 beta) is equal to

If cos(alpha+beta)=0 then sin^(2)alpha+sin^(2)beta

If cot(alpha+beta)=0 then sin(alpha+2 beta) is equal to a.sin alpha b.cos2 beta c.cos alpha d.sin2 alpha

If cot(alpha+beta)=0\ t h e n\ "sin"(alpha+2beta) is equal to a. sinalpha b. cos2beta c. cosalpha d. sin2alpha
