If sin (A+B)= cos (A-B) = 1 , then

In the ambiguous case, it two triangles are formed with a, b, A, then that the sum of areas of these triangles is 1/2 b^(2) sin 2A .

In the ambiguous case, it two triangles are formed with a, b, A, then that the sum of areas of these triangles is 1/2 b^(2) sin 2A .

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^(@).

If A = 2 tan^(-1) ( 2 sqrt2 -1) " and " B = 3 sin ^(-1) ( 1/3) + sin^(-1) ( 3/5) ", then show " A gt B .

If sin(A-B)=1/2 and cos(A+B)=1/2 , find A and B.

If a = sin^(-1) (sin 5) and b = cos^(-1) (cos 5) then value of a^2 b^2 is

A can run 22.5 m in a certain time while B runs 25 m in that time. In a kilometre race B beats A by how many metres :
