`sinA . cosC+ cos A. sinC=`

In a triangle Delta ABC, angleB = 90^(@) and tanA = sqrt""3 then what is the value of sinA.cosC + cosA.sinC?

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

In triangle ABC , right angled at B, if tanA =1/2 , then the value of (sinA(cosC + cosA))/(cosC(sinC - sinA)) is: triangle ABC में B एक समकोण है यदि tanA =1/2 तो (sinA(cosC + cosA)) /(cosC(sinC - sinA)) का मान क्या होगा ?

In a /_\ABC , cosec A[sinB.cosC+cosB.sinC]= (A) c/a (B) a/c (C) 1 (D) none of these

If A+B+C=pi , prove that : cosA sinB sinC +cosB sinC sinA+cosC sinA sinB=1+cosA cosB cosC .

Let ABCD be a cyclic quadrilateral then Statement:1 sinA + sinB+ sinC + sinD=0 and Statement:2 cosA + cosB + cosC + cosD=0

If A+B+C = pi , prove that : cosA- cosB - cosC = 1-4sinA//2cosB//2cosC//2 .

Using properties of determinant. Prove that | [sinA, cosA, sinA + cosB], [sinB, cosA, sinB + cosB], [sinC, cosA, sinC + cosB] | = 0

If A+B+C=pi , prove that : (cosA)/(sinBsinC) + (cosB)/(sinC sinA) + (cosC)/(sinA sinB) =2 .

In a DeltaABC , if a = 18, b = 24, c = 30, find (i) sinA, sinB, sinC (ii) cosA, cosB, cosC
