How do I know that the following equation is true:
PSYCHO15rus [73]

Answer:

<u>Half angle Identity for cosine</u>:

$\cos \left(\frac{\theta}{2} \right)=\pm \sqrt{\frac{1+\cos(\theta)}{2} } $

\text{Note that it is} \pm \text{because we don't know which Quadrant the half-angle is, }\text{the information of}\cos(\theta) \text{is not enough to conclude the angle}

$\frac{\pi}{8} \text{ is a Quadrant I angle, therefore, positive}$

$\cos \left(\frac{\pi}{8} \right)=\sqrt{\frac{1+\cos(\frac{\pi}{4} )}{2} } $

The equation is true.

How would you explain to solve proportions
Over [174]

Answer:

Solving proportions is simply a matter of stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying, and solving the resulting equation.

Example

1)

\frac{2}{3}  =  \frac{4}{6}

2)

\frac{5}{15} =   \frac{1}{3}
