(28) If `1+sin^(2)alpha=3Sin alpha cos alpha` then value of `cotalpha`

If 1+sin^(2)alpha =3 sin alpha cos alpha , then values of cot alpha are

If 1+sin^(2)alpha=3sin alpha cos alpha , then values of cot alpha are (a) -1,1, (b) 0,1, (c) 1,2, (1) -1,1

If 1+sin^2alpha=3sinalphacosalpha , then the values of cotalpha are

If sin^(2)alpha+ sin alpha=1 , then the value of cos^(4) alpha+ cos^(2) alpha is ________

If 2(sin alpha)/(1+cos alpha+sin alpha)=y then value of (1-cos alpha+sin alpha)/(1+sin alpha) is

If sin alpha sin beta-cos alpha cos beta+1=0, then the value of 1+cot alpha tan beta is

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

If sin alpha/2 + cos alpha/2=1.4 , then: sin alpha cos alpha =

If x sin ^ (3) alpha + y cos ^ (3) alpha = sin alpha cos alpha and x sin alpha-y cos alpha = 0 then x ^ (2) + y ^ (2) =
