In mathematics, a bearing is the angle in degrees measured clockwise from north ... work out problems with triangles using the sine or cosine rule: ...

Wheat flour or chalk dust will give you an angle of 45 degrees, dry sand 34 degrees ... the projection of that helix is a sine wave from one direction, and a cosine wave from the other.

Calculate the angle QPR. Give the answer to one decimal place. Label the sides of the triangle \(o\), \(a\) and \(h\). Next choose the correct ratio from \(s^o_h~c^a_h~t^o_a\). In the triangle the ...

His latest post doesn’t disappoint and shows how he uses the CORDIC algorithm to generate very precise sine and cosine waves ... the angle is scaled so that 360 degrees is a full 24-bit word ...
