Issue

I can easily draw a sin cos or tan graph, with no issues.
However when a sin or cos graph is reflected in the x-axis, my troubles start,
as for some reason i dont find the x-int, max and min?

for y-int and endpoints i let the x value of equation =0  (so i still get that right)

for x-ints, i let the equation =0, but for some reason it never turns out correct.  [im fine with exact value's etc)

any techniques for when reflected in y-axis.

Its been there ALLLLLLLL year, and i notice, the day before the EXAM !
LOL !

Yea, much easy. I spent about 2 hours in the last two days trying to speed up my trig graphs,
because it always takes me double the amount of marks.

Also, I have a feeling that it (might) pop-up on the Exam 1 this year, as it hasn't came last two yearsor so..
