Web\$\begingroup\$ To add to this: as you do your routing on a fixed grid, parallel lines will be at least 1 gridmark away. If they make a corner together a 45° angle gives the most space between those two tracks on the diagonal. Different angles may require that these tracks start farther apart to ensure minimum spacing, resulting in less dense routing than optimal. WebApr 14, 2024 · The concept of reference angle can be understood from the diagram above. The reference angle of the X-angle is the Y-angle. ... If the initial angle value is more …
WebThe reference angle is always positive. In other words, the reference angle is an angle being sandwiched by the terminal side and the x-axis. It must be less than 90 degree, … WebThe angle 135° has a reference angle of 45°, so its sin will be the same. Checking on a calculator: sin(135) = 0.707. This comes in handy because we only then need to memorize the trig function values of the angles less than 90°. The rest we can find by first finding the reference angle.
