Question

Sin (a-b)=1,cos(a-b)=1 find a,b

Answer 1

Answer:

a=45 b=45

Step-by-step explanation:

By the above equation we can solve this

Answer 2

Step-by-step explanation:

$\sin(a - + b) = 1 \\ = > \sin(a +b ) = \sin(90) \\ = > a + b =9 0 - - - - - - (1) \\ \\ \cos(a - b) = 1 \\ = > \cos(a - b) = \cos(0) \\ = > a - b = 0 \\ = > a = b - - - - - - - (2) \\ the \: value \: of(a)put \: in \: (1) \\ = > 2b = 90 \\ = > b = 45 - - - - - (3) \\( 2) \: a = b \\ so \: a = 45 \\ \\ \\ your \: ans \: a = 45 \: b = 45$
