Evaluate :

CosA - SinA = 1 ,then find the value of CosA + SinA

If sinA=cosA,then find the value of sin 2A.

If sec A= 2, then find the value of (1)/(cotA)+(cosA)/(1+sinA)

If sinA+cosA=(3)/(5) , then find the value of sinA-cosA .

In tanA=5/12 then the value of (cosA-sinA) cosec A is…….

If 3 tan A=4 , then find the value of (2 sinA-7 cos A)/(3 cosA+4) .

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 ?

if SinA = 4/5 then find (1-SinA)/(1+CosA)

If sinA+cosA=sqrt(2), then the value of cos^(2) A is
