If `alpha+beta= 90^0`, find the maximum value of `sin alpha sin beta`.

If alpha+beta=90^(@) ,find the maximum and minimum values of sin alpha sin beta

If alpha+beta=90^@ , then find the maximum and minimum values of sin alpha sin beta .

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

Ifsin^(4)alpha+cos^(4)beta+2=4sin alpha cos beta,0<=alpha,beta<=(pi)/(2) then find the value of (sin alpha+cos beta)

If alpha , beta are complementry angles such that bsin alpha = a , the find the value of (sin alpha cos beta - cos alpha sin beta) .

If alpha+beta=90^@ , and alpha=2 beta , then the value of 3 cos^2 alpha-2 sin^2 beta is: यदि alpha+beta=90^@ , और alpha=2 beta , तो 3 cos^2 alpha-2 sin^2 beta का मान ज्ञात करें:

If alpha+beta=90^(@),alpha=2beta , then find the value of cos^(2)alpha+sin^(2)beta .

If 3sin alpha = sin beta!=0 , then the value of |(tan((alpha + beta)/2))/(tan((alpha-beta)/2))|

If cot(alpha+beta)=0, then write the value of sin(alpha+2 beta)
