Answer:
sin(135)
= sin (90 + 45) // sin(a + b) = sin(a)cos(b) + cos(a)sin(b)
= sin(90)cos(45) + cos(90)sin(45)
= ( 1 x 1/√2) + (0 x 1/√2)
= 1/√2
= (√2)/2

Answer:
Find the value of sin 135.
sin(135)
= sin (90 + 45)
sin(a + b) = sin(a)cos(b) + cos(a)sin(b)
= sin(90)cos(45) + cos(90)sin(45)
= ( 1 x 1/√2) + (0 x 1/√2)
= 1/√2
