This is exactly the homework I am doing today 😊 I appreciate how logically you organize graph transformations. One of those rare instances where a video being predictable is a *good* thing!

If only i had teachers like u during my schooling days...i would hav loved maths so much....teachers those days were selfish i supose or just do not know the proper technik of teaching...keep on with yr good work...i believe many students there benefit from yr videos👍👍👍

Notification squad! ❤️ Will watch later next week, in time for the trig chapter for my Precalculus study. Thank you for this, Professor!

Professor Leonard, thank you once again for another off the learning charts video/lecture on How to Graph the Cosecant and Secant Functions in Trigonometry/Precalculus. Using the Sine/Cosine graphs these two classical trig functions are simple to graph and analyzed.

Thank you professor your videos helps me a lot I’m so appreciate, next Tuesday I have calculus2 exam on substation by parts, up to 7.4 topic I feel it would be easy with your explaining

Have you considered using a lavalier mic for recording these? It would up your production value considerably. Don’t get me wrong, your content is awesome. Just thinking the lav mic would make your audio sound super clear. Regardless, thanks for all you do. Loving the trigonometry content!

this is too easy. plz do a short video series on Inter-universal Teichmuller theory!

For the graph of y = 4sec(1/2x), why do we not take the reciprocal of the non-zero points, i.e., (0, 4), (2pi, -4), and (4pi, 4)? If the secant graph is a true reciprocal of the cosine graph, wouldn't these points map to (0, 1/4), (2pi, -1/4), and (4pi, 1/4) respectively?
