0:10. Hi sir, this is my first time seeing the co-function, do you have a video explaining it?

[oscarjones]

for the domain for cosec(x) would you not include that x is not equal to zero aswell?

Hi do you have a video on how to graph these functions on a graphic calculator

[mrfreerunners]

I've watched this video and understood it, but I am going to skip the questions as you did :)

hi sir, you know for ex 6b qu10c, I really dont understand how you do it because surely the maximum value would be 1/- infinity and minimum value would be 1/infinity as 1+2sec theta has asymptotes that means it carries on forever in the y direction???

However PMT says max is 1/3 and minimum is -1

btw i understand how to do the smallest positive values of theta bit, its just the finding maximum/minimum values bit which I dont understand

Do we need to know the cofunction identities with secx and tanx?

This is great! will all of this content also be applicable to AQA exams?
