For the following exercises, match each trigonometric function with one of the graphs in Figure 18.
f(x) = tan x
Consider the following trigonometric function:
f(x) = tanx
To acknowledge the graph among the provided graphs in textbook, first sketch the graph of above function,
Put x = π/3 in the above function,
f(-π/3) = tan(-π/3)
= -tan(π/3)
= -√3
= -1.732
Put x = π/4 in the above function,
f(-π/4) = tan(-π/4)
= -tan(π/4)
= -1
Put x = 0 in the above function,
f(0) = tan(0)
= 0
Put x = π/6 in the above function,
f(π/6) = tan(π/6)
= 1/√3
= 0.5774
Put x = π/4 in the above function,
f(π/4) = tan(π/4)
= 1
Put x = π/3 in the above function,
f(π/3) = tan(π/3)
= √3
= 1.732
Now draw the table for the above values of function,
x | -π/3 | -π/4 | 0 | π/6 | π/4 | π/3 |
f(x) | -√3 | -1 | 0 | 1/√3 | 1 | √3 |
Now plot the graph with the table,
Hence it is cleared that the graph I provided in the textbook is the graph of the function
f(x) = tanx.
Hence it is cleared that the graph I provided in the textbook is the graph of the function
f(x) = tanx.
