This function uniquely determines the angle (-180,180] in degree or(-pi, pi] in radian from sine and cosine values. Usage: theta=angleCalc(S,C,out_mode) S: sin value of the angle C: cos value of the angle out_mode: 'deg' OR 'rad' the default output mode is in degree Example...
If sin theta = - 12/13; 270 deg < theta < 360 deg, find theta. Find f . f ''(theta) = sin theta + cos theta, f(0) = 1, f '(0) = 3 If H (theta) = theta cos theta, find H' (theta) and H'' (theta). If \tan \theta ...
