Question

if sin(A+B)=1,cos(A-B)=1,find the value of A and B.
plz give answer with detail..​​

Answer 1

Step-by-step explanation:

sin (A+B) =1 ,

so, sin 90 = 1

cos (A- B) =1 ,

cos 0 = 1 therefore A = 45 and B = 45

Answer 2

Answer:

The values of A and B are equal. Both are equal to 45°.

Step-by-step explanation:

We know that,

sin 90 = 1

Therefore,

A + B = 90 .... (1)

Also,

cos 0 = 1

Therefore,

A - B = 0 .... (2)

Adding (1) and (2),

we get,

2A = 90

A = 45°

Similarly,

B = 45°
