If `(1-cosa-tan^2\ a/b)/(sin^2 (a/2))=(k cosa)/(w+p cosa)` where `k, w and p` have no common factor other than 1, then the value `k^2 + w^2 + p^2` is equal to

If sin A=a cos B and cosA=b sinB then, (a^2 - 1) tan^2 A+(1 -b^2)tan^2B is equal to

If sin A=a cos B and cosA=b sinB then, (a^2 - 1) tan^2 A+(1 -b^2)tan^2B is equal to

1-sin^(2)A/(1+cosA)=cosA

If sin A,cosA and tan A are in G.P. then cot^6A-cot^2A is equal to

If (cosA)/(1-sinA)=tan(k+A/2), then k=

sin A=1/2, cosA=?

Prove: (1+cosA)/(sin^2A)=1/(1-cosA)

int_(0)^( pi)sqrt((cos x+cos2x+cos3x)^(2)+(sin x+sin2x+sin3x)^(2))dx is equal to ((pi)/(k)+w), where k and w are positive integers,find the value of (k^(2)+w^(2))

If sinA = cosA , find the value of 2 tan^(2)A+sin^(2)A-1 .
