Trisectrix of MacLaurin
High Quality Content by WIKIPEDIA articles! In geometry, the trisectrix of Maclaurin is a cubic plane curve notable for its trisectrix property, meaning it can be used to trisect an angle.

When k = a, the curve is the Trisectrix (Fig. 30).f Fig. 30 The Trisectrix This curve
can be used for trisecting an angle, as follows: Make an angle BAR equal to the
given angle, with AR equal to the radius a (Fig. 30). Join R to O, the centre of the

An algebraic system of conic sections, and other curves
To find the polar equation of the Trisectrix. Let z X O P = 0, and O P = r ; then r=
OQ+PQ according as P is taken in O Q or O Q produced. But O Q = 2Rcos. 6, and
P Q = R, r = 2R cos. e + R, the equation required. The Use of the Trisectrix. (Fig.

This is the Trisectrix of Maclaurin (Colin Maclaurin, 1698-1746) and is easily
drawn with a pair of dividers. Start with a semicircle and erect a perpendicular
bisector of segment CO at B (Figure 1.17). For a given angle 0, the point on the ...

The trisectrix, an example of a pedal curve Maclaurin trisectrix; we will explain
this later. Let us first derive the equation of the trisectrix. We choose a coordinate
system at O with the line FO as x1-axis, oriented such that D =(−p,0) and F =(−2p,

When a = 26 the curve is called the ' Trisectrix' since it can be used to trisect a
given angle as in Ex. 8. Ex.6. Trace the cardioid accurately, taking a = 10 units
and giving 8 the values 0, 20°, 40°, ... and inserting intermediate values if it
seems ...
