I am an atheist, but when an exam is in progress I think of each of my students, individually, call out their name and send them positive energy ...
I hope the paper is disgustingly beautiful...

1/(1-sinx) ...

multiply top and bottom by (1+ sinx), simplify and split the fraction.

(there 2 more ways but they are too advanced.)

will send some energy too (I am off tomorrow)

t sub is the one taught in this country but the method I suggested I think it is better ...

there is also another method which only the clever people use ...

I have one way which is better but involves splitting into 2/3 parts then looping. Very very quick though. I think ...nvm im doing it wrong innmy head😂
