SOLUTION:

Step 1:

In this question, we are meant to find the value of:


\sin 45^0

Step 2:

From 4- figure table,


\sin 45^{0\text{ }}\text{ = 0. 7071}

In Surd form,


\sin 45^0\text{ = }\frac{1}{\sqrt[]{2}}

CONCLUSION:


\begin{gathered} \sin 45^0\text{ = 0.7071 ( 4 -figure table)} \\ \sin 45^0\text{ = }\frac{1}{\sqrt[]{2}}\text{ ( surd form )} \end{gathered}
