If in triangle ABC,/_C=45^(@) then find the range of the values of sin^(2)A+sin^(2)B

If in triangle A B C ,/_C=45^0 then find the range of the values of sin^2A+sin^2Bdot

If in triangle A B C ,/_C=45^0 then find the range of the values of sin^2A+sin^2Bdot

If in triangle A B C ,/_C=45^0 then find the range of the values of sin^2A+sin^2Bdot

In a triangle ABC, if A=(pi)/(4), then the range of (sin^(2)B+sin^(2)C) is

If A,B,C are the angles of a triangle, show that that greatest value of sin 2A+ sin 2B+ sin 2C "is" (3 sqrt(3))/(2)

a, b, c are the lengths of three sides of a DeltaABC . If a, b, c are related by the relation a^(2)+b^(2)+c^(2)=ab+bc+ca , then the value of (sin^(2)A+sin^(2)B+sin^(2)C) is

In Delta ABC if a=2,b=sqrt(6) and c=sqrt(3)+1, then sin^(2)C-sin^(2)A

In triangle ABC, if a^(2) + b^(2) +c^(2) -bc -ca -ab=0, then the value of sin ^(2)A+ sin ^(2)B+sin ^(2)C is -

(i) If in a triangle ABC, a^(4) + b^(4) +c^(4) - 2b^(2) c^(2) -2c^(2)a^(2)=0 , then show that, C=45^(@) or 135^(@) . (ii) In in a triangle ABC, sin^(4)A + sin^(4)B + sin^(4)C = sin^(2)B sin^(2)C + 2sin^(2) C sin^(2)A + 2sin^(2)A sin^(2)B , show that, one of the angles of the triangle is 30^(@) or 150^(@)
