Question

what is the value of sin 45 + theta into cos 45 minus theta​

Answer 1

Answer:

The value is 1/2+cos theta×sin theta

Answer 2

I think your question is Sin ( 45° + ∅ ) - Cos ( 45° - ∅ )

.....

Sin ( 45 + ø ) × Cos ( 45 - ø )

Sin ( 45 + ø ) × Sin ( 90 - ( 45 - ø )) { Cos ø = Sin ( 90 - ø ) , ø = ( 45 - ø ) }

Sin (45 + ø ) × Sin ( 45 + ø )

Sin²(45 + ø)
