If `A=580^0`, prove that `2 sin(A/2)=-sqrt(1+sinA)-sqrt(1-sinA)`

sqrt((1+sinA)/(1-sin A ))=

sqrt((1+sinA)/(1-sinA))

If 2 sin""A/2=sqrt(1+sinA)+sqrt(1-sinA,)then A/2 lies between,

If A=580^(0) then -sqrt(1+sinA)-sqrt(1-sinA)=

Within what limits must A/2 lie if 2sin(A/2)=sqrt(1+sinA)-sqrt(1-sinA)

Prove that sqrt((1+sinA)/(1-sinA))=(1+sinA)/cosA .

In any triangleABC , prove that (sqrt(sinA)-sqrt(sinB))/(sqrt(sinA) + sqrt(sinB)) = (a+b-2sqrt(ab))/(a-b) [Hint : (a-b)^(2) = a^(2)+b^(2)-2ab ]

In any triangleABC , prove that (sqrt(sinA)-sqrt(sinB))/(sqrt(sinA) + sqrt(sinB)) = (a+b-2sqrt(ab))/(a-b) [Hint : (a-b)^(2) = a^(2)+b^(2)-2ab ]

Prove that: sin^2(pi/8+A/2)-sin^2(pi/8-A/2)=1/sqrt(2)sinA
