sin^(-1)((1)/(sqrt(5)))+sin^(-1)((1)/(sqrt(10)))=(pi)/(4)

2 (sin A) / (2) = - sqrt (1 + sin A) -sqrt (1-sin A)

If sin A=(1)/(sqrt(5)) and sin B=(1)/(sqrt(10)) ,find the values of cos A and cos B .Hence using the formula cos(A+B)=cos A cos B-sin A sin B, show that (A+B)=45^(@).

Sin (A + B) = 1/(sqrt2) Cos(A - B) = (sqrt3)/2

If sin A=(2)/(sqrt(5)) and cos B=(1)/(sqrt(10)), where A and B are acute angles,then what is the value of A+B

sin^(-1)(1/sqrt5)+cos^(-1)(3/sqrt(10))

If sin A=(1)/(sqrt(10)) and sin B=(1)/(sqrt(5)), where A and B are positive acute angles,then A+B is equal to
