2 dni temu · The small-angle approximation is the term for the following estimates of the basic trigonometric functions, valid when \(\theta \approx 0:\) \[\sin \theta \approx \theta, \qquad \cos \theta \approx 1 - \frac{\theta^2}{2} \approx 1, \qquad \tan \theta \approx \theta.\]
3 dni temu · \[ \text{arcsin}(\sin(\theta)) = \theta \] Example Calculation. Consider calculating the sine and arcsine of \( 0.5 \) radians. The sine of \( 0.5 \) radians is approximately \( 0.47942554 \), and the arcsine of \( 0.5 \) gives an angle of approximately \( 30 \) degrees or \( 0.52359878 \) radians.
