3. Compare the function y = tanx and its reciprocal. Identify two similarities and two differences between the functions.

The similarities are;

1) The tangent slope of the tangent graph and the cotangent graph are always the same sign through out

2) The period of each trigonometric ratio cot and tan is π/2

The differences are;

1) The sign of tangent function always positive while that of the cotangent function always negative

2) Where the value of cot x ranges from undefined to 0, the value of tan x ranges from 0 to undefined in the same domain
