Question

what is sin 45 degree equal to ??

Answer 1

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:

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