Two forces of magnitudes 7N and 3N act at right angles to each other. The angle \(\theta\) between the resultant and the 7N force is given by
cos\(\theta\) = \(\frac{3}{7}\)
sin\(\theta\) = \(\frac{3}{7}\)
tan\(\theta\) = \(\frac{3}{7}\)
cot\(\theta\) = \(\frac{3}{7}\)
解释
\(\theta\) = tan-1\(\frac{3}{7}\)
