If `0^(@) lt A, B lt 90^(@)`, such that `cos A = 5/13, sin B = 4/5`, find `sin (A-B)`.

If 0 lt A, B lt 90^(@), cos A= (5)/(13) and sin B =(4)/(5) then find sin (A+B) .

If 0^(@) ltAltBlt90^(@) show that sin A lt sin B

If A>0^@ , B<90^@ , such that cos A=(5)/(13) and sin B=(4)/(5) , then the value of sin(A-B)

If 0^(0)ltA,Blt90^(0) ,Such that cos A=(5)/(13) and sin B=(4)/(5) ,then the value of sin(A-B) (8)/(65) (32)/(65) (24)/(65) (16)/(65)

0 lt A lt 90^@ : 0 lt B lt 90^@ , sin A=12/13 and cos B= 4/5 . Find the vaue of sin (A+B).

If 180^(@) lt A lt 270^(@) , 270^@ lt B lt 360^(@) and sin A = -5//13 , sec B=5//4 , then sin A cos B+ cos A sin B=
