Graphing Trigonometric Functions, Phase Shift, Period, Transformations, Tangent, Cosecant, Cosine

[@TheOrganicChemistryTutor]

Hi everyone, I just want to mention a few corrections that you should be aware of. At 33:24, it should be pi/2 and 3pi/2 on the x-axis instead of pi/4 and 3pi/4. At 56:36, it should be 3pi/4 instead of 3pi/2.

[@NeonHelix20]

The Organic Chemistry Tutor at 15 minutes why does cosine start at 5 but the problem before that sine starts at the vert shift value

[@dannyfarley21]

Shouldn't the final tan graph have a phase shift to the right pi?

[@catvyhuynh7359]

I was about to ask you about that mistake, anyway, thanks for correcting it

[@catvyhuynh7359]

At 33:25, I wonder why the points between pi and 2 pi are pi/4 and 3pi/4 respectively. They should be pi/2 and 3pi/2, right? Am I wrong?

[@MsSade-ue7qq]

What about at 25:19? Period of 2pi yet the x axis expands to 3pi?
