ative, and the value of y will be imaginary.This shows that there is no value of ?/, and therefore no pointof the curve, except when x is contained between the limits 2 < .T < 22. We now find the following sets of corresponding values ofX and y: 2 3 4 G 8 10 12 14 16 18 20 21 23 5.0 9.4 11.0… … EXERCISES. Construct the loci of the following equations to rectangu-lar co-ordinates: 1. y = Zx^ - X -10. 2. ^ = sin X. 3. y = cos X. Note. Iu the last two exercises we should, in rigor, adopt the unitradius, 57° 18, as the unit of x. But a more convenient and equallygood course will be to take…
