i want to convert the value of

sin45

it gives the value of

0.850903534 of sin45(which is in radian).

i have to use its degree 's value

mean to say that

0.70710678118654752440084436210485 which is its degree value.

what should i do?

i am trying this

0.850903534 * 180 / Pi

but

it gives this 48.753180728611482440956052242364 which is in degree but not actual result
