Write (55)/(-66) in simplified form

Write (27)/( 81) in simplified form.

Simplifying the following: abs({:("cosA "," sinA"),(sinA,-cosA):})

In a triangle ABC,k right angled at B, if tan A = (1)/(sqrt3). Find the value of cos A.cosC-sinA.sinC.

The simplified value of (SecA-cosA)^(2)+("cosec" A-sinA)^(2)-(cotA-tanA)^(2) is

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

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

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 ?

The simplified value of 1- (sin^(2)A)/(1+ cosA) + (1+ cosA)/(sinA) - (sinA)/(1- cosA) is:
