" 7.If "sin alpha=(1)/(sqrt(2))" and "cos beta=(1)/(sqrt(2))" ,then find the value of "(alpha+beta)" ."

If sin alpha=(1)/(sqrt(10)) and sin beta=(1)/(sqrt(5)) then prove that alpha+beta=(pi)/(4)

If sin alpha cos beta=-(1)/(2) then find the range of values of cos alpha sin beta

If sin alpha cos beta=-(1)/(2) then find the range of values of cos alpha sin(beta

If sin alpha cos beta=-(1)/(2) then find the range of values of cos alpha sin beta

In sin alpha+ sin beta=(1)/(2) and cos alpha+ cos beta =(5)/(4) , find the value of tan alpha+tan beta .

If sin(alpha+beta)=1 and sin(alpha-beta)=(1)/(2), where 0<=,beta<=(pi)/(2) ,then find the values of tan(alpha+2 beta) and tan(2 alpha+beta)

Le alpha and beta be such that pi

Given that sin alpha = (sqrt(3))/(2) and cos beta = 0 , then the value of beta - alpha is

Given that sin alpha = (sqrt(3))/(2) and cos beta = 0 , then the value of beta - alpha is

If sec(alpha-beta)=sqrt(2) and sin(alpha+beta)=(1)/(2) , then find the least positive values of alpha and beta .
