amazing video only criticism is that the last question's answer is 90 not y - 90, i believe you put the wrong relationship between sine and cosine

10:53 The second value of cot (π/3) why is it 1/(π+√3) instead of π+1/√3 ?

Hi. Thank you so much for this video. At 1:19:37 why does the solution slide only have an answer of x = 135 and 315? Why have they not included 38.7 and 219. Thanks!

Mrs you know for sec(pi/6) shouldn’t the answer be 2sqrt3/3 at 10:59

At 44:25 would it be correct after converting 1-cos^2x into sin^2x to convert cosx into sinx/tanx then dividing sin^2x by sinx/tanx to find the answer.

I've got a question at 23:00 wont the graph be lower because if 4cosec(x) = 4(1/sin(x)) won't that be 4/sin(x)?

hey first off thank you, but i want to ask. Around 10 minutes, the second column, how do we know when to use the graph method and when not?

Hello ma’am, at 10:54, shouldn’t the answer be 3/sqrt(3), why was it written as sqrt(3)

at 14:11 shouldnt f(x)be less than -1 ?

In the last question. Isn’t it supposed to be sin(x) is equal to cos(x-pi/2)

1:37:19 sin(x) should be cos(x-pi/2) and cos(x) should be sin(x+pi/2)
