If `A(sinalpha,(1)/(sqrt(2)))" and "B((1)/(sqrt(2)),cosalpha)-pilealphalepi` are two points on the same side of the line `x-y=0`. Then `alpha` belongs to the interval

If P (sin theta, 1//sqrt(2)) and Q(1//sqrt(2), cos theta), -pi le theta le pi are two points on the same side of the line x-y=0, then theta belongs to the interval

If P (sin theta, 1//sqrt(2)) and Q(1//sqrt(2), cos theta), -pi le theta le pi are two points on the same side of the line x-y=0, then theta belongs to the interval

If A((sin alpha)/3 - 1,(cos alpha)/2 - 1) and B(1,1) alpha in [ -pi,pi] are two points on the same side of the line 3x - 2y +1 = 0 then alpha belongs to the interval

If A((sin alpha)/3 - 1,(cos alpha)/2 - 1) and B(1,1) alpha in [ -pi,pi] are two points on the same side of the line 3x - 2y +1 = 0 then alpha belongs to the interval

If A((sin alpha)/3 - 1,(cos alpha)/2 - 1) and B(1,1) alpha in [ -pi,pi] are two points on the same side of the line 3x - 2y +1 = 0 then alpha belongs to the interval

If (2sinalpha)/(1+cosalpha+sinalpha) =x, then (1-cosalpha+sinalpha)/(1+sinalpha) =

If (2sinalpha)/(1+cosalpha+sinalpha)=x then find (1-cosalpha+sinalpha)/(1+sinalpha)

If A=[cosalpha+sinalpha,sqrt(2)sinalpha; -sqrt(2)sinalpha,cosalpha-sinalpha] , prove that A^n=[cosn\ alpha+sinn\ alpha, sqrt(2)sinn\ alpha; -sqrt(2)sinn\ alpha, cosn\ alpha-sinn\ alpha] for all n in Ndot
