#### 11.2.7 bdCurve

• bdCurve( <f(t)>, [options] )
• Description: defines a curve in the space, parametrized by $f\left(t\right)=\left[x\left(t\right)+i*y\left(t\right),z\left(t\right)\right]$ or $f\left(t\right)=M\left(x\left(t\right),y\left(t\right),z\left(t\right)\right)$, where $x\left(t\right)$, $y\left(t\right)$ and $z\left(t\right)$ are functions of one variable $t$. bdCurve options:
• t := < [tmin, tmax] >. Interval for the paraameter $t$, [-5,5] by default.
• nbdot := < positive integer >. Defines the number of points, $25$ by default.
• That macro calls bdLine, options of bdLine can then be used.
