Graphing a reciprocal function via Table
Sin function
x or y | 0 | 6π | 3π | 2π | 32π | 65π | π | 67π | 34π | 23π | 35π | 611π | 2π |
---|
y=sinx | 0 | 1/2 | 23 | 1 | 23 | 1/2 | 0 | -1/2 | 2−3 | -1 | 2−3 | -1/2 | 0 |
y=cscx | undef | 2 | 32 | 1 | 32 | 2 | undef | -2 | 3−2 | -1 | 3−2 | -2 | undef |
notice how the table is intervals with unit circle, but there is no xpi/4 ratios
Cos function
x or y | 0 | 6π | 3π | 2π | 32π | 65π | π | 67π | 34π | 23π | 35π | 611π | 2π | | |
---|
y=cosx | 1 | 23 | 1/2 | 0 | -1/2 | 2−3 | -1 | 2−3 | -1/2 | 0 | 1/2 | 23 | 1 | | |
y=secx | 1 | 32 | 2 | undef | -2 | 3−2 | -1 | 3−2 | -2 | undef | 2 | 32 | 1 | | |
Tan function
x or y | 0 | 4π | 2π | 23π | π | 45π | 23π | 47π | 2π | | | | | |
---|
y = tanx | 0 | 1 | undef | -1 | 0 | 1 | undef | -1 | 0 | | | | | |
y = cotx | undef | 1 | 0 | -1 | undef | 1 | 0 | -1 | undef | | | | | |
