User2983 Posted March 13, 2005 Report Share Posted March 13, 2005 Does anyone know the trigonometry identity for sin(theta)*cosine(theta)? Link to comment Share on other sites More sharing options...
zadojla Posted March 13, 2005 Report Share Posted March 13, 2005 Do you mean: sin^2(theta) + cos^2(theta) = 1 Link to comment Share on other sites More sharing options...
User2983 Posted March 14, 2005 Author Report Share Posted March 14, 2005 No, I rechecked it and it just says sin(theta)*cosine(theta) Link to comment Share on other sites More sharing options...
OpenMind5 Posted March 14, 2005 Report Share Posted March 14, 2005 Sin(theta)Cos(theta)=Sin(theta)Cos(theta) There is no trigonometric Identity that fits your senerio... 2(Sin(Theta)Cos(theta))= Sin(2(theta)) Op5 Link to comment Share on other sites More sharing options...
C1ay Posted March 14, 2005 Report Share Posted March 14, 2005 Your function is not an identity. You can learn the identities here. Link to comment Share on other sites More sharing options...
Qfwfq Posted March 15, 2005 Report Share Posted March 15, 2005 Try half the sine of twice theta... Link to comment Share on other sites More sharing options...
