Sin (135)

= Sin (90 + 45)

= Sin (90) cos (45) + cos (90) sin (45)

= (1 x 1 / š2) + (0 x 1 / š2)

= 1 / š2

= (à š2) / 2

Sin 135 ° = Sin 45 ° = 1/2 ° 2

Sin (135) = Sin (90 + 45)

= Sin (90) cos (45) + cos (90) sin (45)

= (1) (1 / š2) + 0

= 1/2

NAS 135 = NAS (180 45)

= + SIN (45) ..... The angle is in the second quadrant where sin +. it is

= 1 / (square root 2) .... special triangle of 45, 45, 90
