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

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

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

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

If sin alpha sin beta-cos alpha cos beta+1=0, then prove that 1+cot alpha tan beta=0

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

(sin alpha)/(1+cos alpha)+(1+cos alpha)/(sin alpha)=2cosec alpha

If sin alpha=1/2 and cos beta=1/2 then alpha+beta=

If (2 sin alpha)/(1 + cos alpha + sin alpha) = 3/4 , then the value of (1 + cos alpha + sinalpha)/(1 + sin alpha) is equal to

(1-2sin^(2)alpha)/(1+sin2 alpha)=(1-tan alpha)/(1+tan alpha)
