If `coa(alpha+beta)+sin(alpha-beta)=0` and `2010tanbeta+1=0` then `tanalpha=`

If cos(alpha+beta)+sin(alpha-beta)=0 and 2010tanbeta+1=0 then tan alpha is equal to

If cos( alpha+beta) + sin(alpha-beta) = 0 and 2010tan beta - 1 = 0 then tan alpha is equal to

If cos( alpha+beta) + sin(alpha-beta) = 0 and 2010tan beta + 1 = 0 then tan alpha is equal to

cos(alpha+beta)+sin(alpha-beta)=0"and"tanbeta=1/2009 ,find tan(alpha)

cos(alpha+beta)+sin(alpha-beta)=0"and"tanbeta=1/2009 then value of tan3α

Let alpha, betain(0,pi/2),3sin(alpha+beta)=2sin(alpha-beta) and tanalpha=ktanbeta then the value of k is

If cos(alpha + beta) =0 , then sin (alpha- beta)= ________

If sin(alpha+beta)=1 and sin(alpha-beta)=1/2 where alpha,beta in [0,pi/2] , then tan(2alpha+beta)=

If cot(alpha+beta)=0, then sin(alpha+2 beta) can be (a)-sin alpha(b)sin beta(c)cos alpha(d)cos beta

If alpha + beta = 90^@ and beta + gamma = alpha then tanalpha-tanbeta=?
