(sqrt2 - sin alpha - cos alpha )/( sin alpha - cos alpha)=

(sqrt2 - sin alpha - cos alpha )/( sin alpha - cos alpha)=

Eliminate alpha , if x = r cos alpha , y = r sin alpha .

Eliminate alpha , if x = r cos alpha , y = r sin alpha .

If x=a sin alpha+b cos alpha and y=a cos alpha-b sin alpha then remove alpha

If x= sin alpha + sin betga , y = cos alpha + cos beta tan alpha + tan beta =

If x sin alpha = y cos alpha, prove that : x/(sec 2alpha) + y/(cosec 2 alpha) = x

If (sin alpha)/(a)=(cos alpha)/(b), then a sin2 alpha+b cos2 alpha=

If p&q are lengths of perpendicular from the origin x sin alpha+y cos alpha=a sin alpha cos alpha and x cos alpha-y sin alpha=a cos2 alpha, then 4p^(2)+q^(2)

If x = sin alpha, y = sin beta, z = sin (alpha + beta) then cos (alpha + beta) =
