Maximum and Minimum Values of Sine and Cosine Functions, Ex 2

[patrickjmt]

you would use derivatives, or you could think about were sin(x) normally has max/mins. then you could set 2x+1 = to those values and solve

[patrickjmt]

@bakingbaker yes, you could, but that is hard to do if you are only starting trigonometry : ) (the target audience here)

My exam is after 3 hours, your video is really helpful!

[RatherBeCancelledThanHandled]

Good videos, I just find it kind of hard to grasp these concepts as they move so quickly, one minute we're using sine to angles of a triangle, the next minute we're using sine to discover how often customers exit and enter a mall. LMAO, It's hard to clearly see how this makes sense.

How do you find max and min when it looks something like sin(2x+1)??

[bakingbaker]

It's been a couple of yours since I've done calculus but couldn't I just take the derivative, find the zeros and plug those answers into the original problem?

patrick I think I love you, thank you!

[Jackychin]

hello, why the period is 2pi/amp of 6/pi?

[patrickjmt]

@MiturBinlsderty im just a nice guy i guess

[bakingbaker]

@patrickJMT Ahh understood, I was under the impression it was for calc 1.

Good teaching but you are just skipping the basics of trigonometry Patrick. You didn't even tell about the sine, cos, tan introduction. Calculus playlists is awesome. Thank u Patrick!! O:-)

cospi is not equal to i'm so confused
