Trigonometric Graphs - GCSE Higher Maths

A video explaining the graphs of y = sinx, y = cosx and y = tanx. In the video we learn how to sketch the graphs, their shape and key points along with how to resolve equations using the graphs. This is suitable for the GCSE higher course.

This could not have been explained any more clearly. Thx for sharing. Such a big help.

This was unbelievably helpful. My teacher is so bad at explaining and I’ve been struggling with the topic of graphing function for weeks. I just watched your other video and this one and now I feel confident for my exam 😭. Thank you!!

[sweetlikeespresso]

I have been watching this topic for days across different videos until I watched this and actually understood. Thank you

[xleoss]

the guy deserves a sub and a like for sure

thank u for saving my life an hour and a half before my trig test😭😭😭

I wish I found this before paper 1 :( I tried revising the estimating with a line but I couldn’t find any resources on that until now

Hey, just got notified by my teacher that you came to our school yesterday....Am so unlucky to miss thatt

[ritu]

i just learnt like 1 hours worth of math in like 20 minutes AMAZINGGG

[cool-td]

thank u so much bruh i was tryna revise this topic the other day and u finally made it

[hutt]

I went from a 4 to an 8 with your vids

[Pegasus]

Can you not delete these videos like the other youtubers do as some of us need it for revising. love the content btw
