Question

Find the value of $\sin {45}^{\circ }+\sin {45}^{\circ }$

Answer 1

$\sin {45}^{\circ }+\sin {45}^{\circ }$

$=\frac{1}{\sqrt{2}}$ + $\frac{1}{\sqrt{2}}(\sin {45}^{\circ }=\frac{1}{\sqrt{2}})$

$=\frac{2}{\sqrt{2}}$

$=\frac{\sqrt{2}\times \sqrt{2}}{\sqrt{2}}(2=\sqrt{2}\times \sqrt{2})$

$=\sqrt{2}$
