Animate math steps Step-by-step math proof

Let be a triangle. The altitudes and intersect at . We will show that also is perpendicular to , i.e. an altitude of .

  • The quadrilateral is cyclic, because . So, also (subtended by the same arc).
  • The quadrilateral is cyclic because opposite angles and are supplementary (). So, angles and are equal.
  • The angles and are equal as vertical angles, i.e. . In the right triangle , we have that , therefore in the triangle it holds that .

We conclude that, ...

RC discharge calculator RC discharge calculator with output on SVG graph (including ability to copy the value on the graph)

For instance, 1  of resistance with 1  of capacitance produces a time constant of approximately 1 seconds. This τ corresponds to a cutoff frequency of approximately 159 millihertz or 1 radians per second. If the capacitor has an initial voltage V0 of 1 , then after 1 τ (approximately 1 seconds or 1.443 half-lives), the capacitor's voltage will discharge to approximately 368 millivolts:

 VC(1τ) ≈ 36.8% of V0
