Find the exact value. if the expression is undefined write undefined. csc 135°
Pepsi [2]
\bf csc(\theta)=\cfrac{1}{sin(\theta)}\\\\
-----------------------------\\\\
csc(135^o)\implies \cfrac{1}{sin(135^o)}\implies \cfrac{1}{\frac{\sqrt{2}}{2}}\implies \cfrac{\frac{1}{1}}{\frac{\sqrt{2}}{2}}\implies \cfrac{1}{1}\cdot \cfrac{2}{\sqrt{2}}\implies \cfrac{2}{\sqrt{2}}
\\\\\\
\textit{now, rationalizing the denominator}
\\\\\\
\cfrac{2}{\sqrt{2}}\cdot \cfrac{\sqrt{2}}{\sqrt{2}}\implies \cfrac{2\sqrt{2}}{(\sqrt{2})^2}\implies \cfrac{2\sqrt{2}}{2}\implies \boxed{\sqrt{2}}
