Given that sin\(\theta\)=a/b ,then tan\(\theta\) is equal to(a) \(\cfrac{b}{\sqrt{a^2+b^2}}\)(b) \(\cfrac{b}{\sqrt{b^2-a^2}}\)(c) \(\cfrac{a}{\sqrt{a^2-b^2}}\)(d) \(\cfrac{a}{\sqrt{b^2-a^2}}\) |

Answer» Correct answer is: (d) \(\cfrac{a}{\sqrt{b^2-a^2}}\) H2=P2+B2 b2=a2+B2 B=\(\sqrt{b^2 -a^2}\) tan\(\theta\) = P/B=a/\(\sqrt{b^2 -a^2}\) |
