This is the best trigonometric video. Everything was explained in a genius way. Thank You so much. 🎉😊

3:11 I remember it by the third letter of their names. cosec has its third letter as s, which means it is reciprocal of sin, and so on for the sec and cot too

Thank you mam. I was really confused by memorising these identities while you maked it simple.

@nicotandotrunz6957 4 года назад

It got difficult towards the end. However the topic in this video is nicely explained. Thank you !

Man or woman, I could listen to the Aussie accent of a math Instructor all day long.

@suyashkhobragade401 3 года назад

3:35 I use, S in sec near to T in tan, and the other, C of cosec near to/or on C of cot, alphabetically

@ghudhdbdndnshsheudhdj838 5 лет назад

Explanation is very clear

7:50 Isnt a negative theta also possible on quadrant two? It goes clockwise if I start from the negative X-axis

@THaWoM 3 года назад

I'm not sure what you mean. That would be 180-theta in quadrant 2, if theta is chosen to be in quadrant 1.

@bobjoe1232 3 года назад

@@THaWoM Ah. So we can only measure from + X axis? See how you have theta (Quadrant 1) and negative theta (quadrant 4) at 7:50 ? Well can I not draw negative theta in quadrant 2? I would just have to go clockwise starting from negative X axis and I would get negative theta in Quadrant 2, no?

@THaWoM 3 года назад

@@bobjoe1232 Yeah, in trig it's always from positive x-axis.
