Here an example is illustrated followed by some problems for you to attempt: A six-meter-long ladder leans against a building. If the ladder makes an angle of \(60^\circ\) with the ground, (1) how far up the wall does the ladder reach, and
2 dni temu · The small-angle approximation is the term for the following estimates of the basic trigonometric functions, valid when \(\theta \approx 0:\) \[\sin \theta \approx \theta, \qquad \cos \theta \approx 1 - \frac{\theta^2}{2} \approx 1, \qquad \tan \theta \approx \theta.\]
