Question

Basic Angles and Radian Measure Help Please

Answer 1

To convert degrees into radians, simply multiply by this constant...
\[\huge \frac{\pi}{180^o}\]

Answer 2

And to convert radians back into degrees, multiply by its reciprocal
\[\huge \frac{180^o}{\pi}\]

Answer 3

Let's try the first one, \(\large 45^o\) into radians.
Multiply the first constant with it...
\[\huge 45^o \times\frac{\pi}{180^o}\]
\[\huge {45^o}\times \frac{\pi}{45^o\times4}\]
\[\huge \cancel{45^o}\times \frac{\pi}{\cancel{45^o}\times4}\]
\[\Huge \color{blue}{\frac \pi 4}\]

Answer 4

Don't need this nooby stuff, just gotta think analytically
