Question:medium

If \(1^\circ \approx 0.01745\) radians, then the approximate value of \[ \sec 29^\circ \] is:

Show Hint

For small values of \(h\) (in radians), \[ \cos(\theta-h)\approx \cos\theta+h\sin\theta. \] This approximation is frequently used in objective examinations to estimate trigonometric values near standard angles.
