" 29.If "a+beta-90^(@)" then maximiun value of "sin alpha sin beta" is: "

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 alpha and beta satisfy sin alpha cos beta=-(1)/(2), then the greatest value of 2cos alpha sin beta is

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 and beta satisfy sin alpha cos beta=-((1)/(2)), then the greatest value of 2cos alpha sin beta is

If alpha,beta are roots of a cos theta+b sin theta=c then value of sin alpha+sin beta&sin alpha sin beta is

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

If alpha+beta=90^@ and alpha=2beta , then the value of 3cos^2alpha-2sin^2beta is equal to:

Let alpha,beta and gamma are the angles of a right angle triangle,then the value of sin alpha*sin beta*sin(alpha-beta)+sin beta*sin gamma*sin(beta-gamma)+sin gamma*sin alpha*sin(gamma-beta)+sin(beta-gamma)*sin(gamma-gamma)*sin(gamma-
