If A,B,C are angles of a triangle then prove that cosA+cos(B-C)=2sinB sinC

Posted by Priyanshi Setia 7 years, 6 months ago

CBSE > Class 11 > Mathematics

1 answers

Susai Raj 7 years, 6 months ago

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

cos(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.

A New Girl In The City 7 years, 6 months ago

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.

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
