Simplify :

`K^2/4 SinA SinB SinC `

In Delta ABC, if (Sin A + SinB + SinC) (SinA + SinB - SinC) = 3SinA SinB then C =

Statement I: If sinA=sinB , cosA=cosB then A= 2np + B Statement II :If A+B+C=90^@ then sin2A+sin2B + sin2C = 4 sinA sinB sinC Which of the above statements is correct?

Find simplified form : ( SinA + CosA )^2 + ( SinA + CosA )^2 =

Consider a DeltaABC satisfying 2aSin^(2)((C)/(2))+2cSin^(2)((A)/(2))=2a+2c-3b SinA, SinB, SinC are in

If A+B+C= pi/2 , show that : cos^2 A + cos^2 B + cos^2 C = 2 + 2 sinA sinB sinC .

If A+B+C= pi/2 , show that : sin^2 A + sin^2 B + sin^2 C=1-2 sinA sinB sinC

If P is the circumcentre of an acute angled triangle ABC with circumredius R. D is the midpoint of BC. Show that the perimetre of triangleABC = 2R(sinA + sinB + sinC) .

In a DeltaABC, sin A sinB sinC is

In triangleABC , which is not right angled, if p=sinA sinB sinC = and q=cosA. cosB. cosC. Then the equation having roots tanA,tanB and tanC is

If A+B+C=pi , prove that : sinA cosB cosC +sinB cosC cosA + sinC cosA cosB = sinA sinB sinC .
