You deserve the best teacher, just saved me from confusion.

[@emilyt7534]

Thank you so much! Watched about five videos before this and none of them explained this concept as well as you. So glad that I found your channel!

[@anniquequarlesvanufford5813]

Well, guess who just saved me from failing my trig exam! My teacher tried to explain this but it never made sense till this video!

[@Punicia]

Thank you Mario. This is the only video that actually helped me with this topic. I appreciate your ability to make the concept very clear when my teacher can't. +1

[@passionatepro5322]

ITS 7:50 IN THE NIGHT AND YOU SIR HAVE JUST SAVED ME. YOU WILL NEVER KNOW HOW GRATEFUL I AM FOR THIS VIDEO LOL

[@AnnetteCompean]

Dude you just helped me so much! Thank you our teacher didn’t really explain this at all!! he gave us one problem and told us to learn from that!!

[@MusanGreen]

You are a born teacher. Thank you so much for all your efforts and dedication.

[@MariosMathTutoring]

You are very welcome

[@DrLiangMath]

Your explanation was so systematic, clear and easy to understand. Thanks👍

[@shashwatpriyadarshi972]

Sir even though Iam a doctor and not a student of mathematics then also I could make sense of it ,that just goes to show what a great teacher you are. Some stupid questions from this doctor- Why are waves represented as sine or cosine functions? Use of integral and differential equations in practical life

[@sonyavalkova6885]

My math test is next period, and thank you so much for saving me to relieve some stress!

Thanks you so much for this video

[@maryangutierrez5878]

can you please explain to me how one can tell if the a value (amplitude) is negative or positive?

[@achyutreddy2007]

From my knowledge, the amplitude is always positive. It's the value of the highest point on the graph subtracted from the midpoint.

[@maryangutierrez5878]

@@achyutreddy2007 i didn’t need this anymore, but thank you so much😭

[@Ro_Show]

Oh my god this saved my grade 🙏. Question however, if you use a positive amplitude on the cosine graph which you did, doesnt that mean that B would be -2pi? Because you said we could use any point when using that one, because it isn’t reflected.

[@Ro_Show]

I mean if you use the maximum on the right instead of the left.**

Hello, do you know how to make it cut off, say from -pi to pi/2 only portion? Thank you!

oh nevermind, its just X value

[@mrbloxcraft5611]

Perfection.

[@TreSwayy]

I'm learning this on Khan Academy and it's so confusing. I find myself in circles where I do understand then i'll just get randomly stumped.

Why is Pi used? I see it in every video and I’m so confused on what to do

Sine starts at origin Cosine starts at maximum

[@yashkirdak8805]

How can I share my question to you sir

[@juantuthree357]

What does “reflected over the x-axis” mean? Anyone?

[@liyajohnson7405]

if a point is reflected over x axis then the x coordinate remains the same but the sign of y coordinate becomes negative. or simply imagine it as a water image of something with respect to the x axis or it gets flipped over the x axis.

[@aadilmiller3899]

well explained sir, but unfortunately I'm having some sort of deficalty with sin and cosine phase shift. this is one of the problems that i'm finding complicated, 3 sin(2x-pi)+2 i can actually find its amplitude, vertical shift and period, I'm just not getting 'WHY' i need to factor out 2 like this ' 2(x-pi/2)' , why can't i just shift the graph by 'pi' unit to the right..?? again, i can figure out all except it's phase shift i would just like some explanation behind that 'factoring out 2' thing, sorry for this long question. ''please some explanation would be helpfull, I'm struggling with it from last 5 days''

[@MariosMathTutoring]

Aadil, you can shift the graph right pi and then horizontally compress the graph by dividing the x values by 2 however it is easier to factor out the two and calculate the period as pi/2 and then shift that graph right pi/2...either way you will get the same graph...I recommend reviewing transformations of parent functions ....hope that helps
