If A,B,C are angles of a triangle then prove that cosA+cos(B-C)=2sinB sinC |
| Answer» We know that A + B +C = 180° (sum of 3 angles of a triangle)So A = 180-(B+C)Also cos(180-X) = -cos X .and\xa0cos(X +/- Y) =cosXcosY -/+ sinXsinY.Now cosA + cos(B-C)= cos{180-(B+C)}+cos(B-C)=--cos(B+C)+cos(B-C)=-(cosBcosC-sinBsinC)+cosBcosC+sinB sinC=-cosBcosC+sinB sinc+cosBcosC+sinB sinC=2sinBsinC.\xa0\xa0\xa0\xa0 | |

What r Coplanar Vectors..?? |
|
Answer» Definition: Vectors parallel to the same plane, or lie on the same plane are called coplanar vectors.It is always possible to find a plane parallel to the two random vectors, in that any two vectors are always coplanar. You can check it on google it explain you very nicely Ok..Thanks By mistake I post here Zero vector or null vector is a vector which has zero magnitude and an arbitrary direction. It is represented by . If a vector is multiplied by zero, the result is a zero vector.I read it from Google so I answer you from that Vectors which lie on the same plane are called co-planor vectors. |

Tany=3tanx , prove tan(x+y)=2sin2y/1+2cos2y |
| Answer» tan (x+y) = (2sin 2y) /(1+2cos2y)L.H.S :-tan (x+y)=(tan x +tan y ) / (1-tan x tan y)Substitute, the value of tan x with (tan y)/3=(tan y/3 +tany) / (1-tan y/3 • tan y)=(tan y + 3tan y) / (3-tan²y)=(4tan y) / (3- tan²y)=(4 sin y/cos y) / (3 - sin²y/cos²y)=(4sin y • cos y) / (2cos² y +cos² y -sin²y)= (2 sin 2y) / (1 + 1 - 2sin²y + cos 2y)= (2 sin 2y) / (1 + 2 cos 2y) ☑️☑️☑️☑️L.H.S =R.H.S ?
