 Question 89040: Can someone tell me if this is correct, and also I need to round it to the nearest tenth but I don't know how.......A plane with an airspeed of 450 mph if flying in the direction N35degrees West....im supposed to express the vector in terms of i&j...... my answer is -450sin35i + 450cos35jAnswer by stanbon(57224)   (Show Source): You can put this solution on YOUR website!I think N35 degrees W is an angle of 135 degrees If your i corresponds to horizontal motion and your j corresponds to vertical motion you might want an answer of 450(icos(135) + jsin(135)) ------------ Cheers, Stan H.
