C++ sine in degrees?

Question

i am trying to find the sine of an angle in degrees.

the C++ function sin() returns the value in radians.

is there anyway to get the sine of 89 in degrees

i know that the sine of 89 in degress is .999847695, but when i do it with the sin(89) function, it returns .8600694058

any suggestions?

Answer 1

use a formula to convert

in C++ sinx accepts x in terms of radians

if x in degrees use
sin(x*pi/180)

that is sin(89*3.14/180)
