I want to evaluate 10*cos(30), the 30 is in degrees.

However, matlab only accept radian, meaning I have to convert the 30

degrees to pi/6 rad.

How do I compute it directly without having to convert to radian

You do not. You have to convert it to radians.

It doesn't ache so much, well ... only at the first time

Check out the functions, 'sind', 'cosd', 'tand', 'cotd', 'secd', and 'cscd'.

(Remove "xyzzy" and ".invalid" to send me email.)
