Trig help someone!

here are a few more for the lonely

y = -sec (x-2/pie) + 2

y=2 cos (3x - 3pie/4) + 1

y = cot (x + pie/3) - 2

y = -2 tan (1/2x - pie/4) +1

y= -3 cos (2x-pie) + 1

i do remember that tan graphs are simular to sin graphs but fliped 90 deg and cot is the opposite of tan and incase you didnt know cos and sec are opposite eachother as well

anyone who is willing to answer my questions? I mean literally answer them, I im you the questions from the book and you give me the right answer? LMK THANKS

you should read the question, it doens't seem to hard, really its pattern matching.

K * TRIGFUNC( (2pi/T)t - Phi ) + Vert

K -- amplitude

T -- period

Phi -- phase (you may want to "bound" the phase, force it be be between -pi and pi)

Vert -- vertical offset (aka DC offset)

* might be + Phi.

now for csc, tan, ctn, sec, you may need to put amplitude as inf, as these all have asymtotes.

graphing is also equally easy. CSC is 1/COS. so any point COS = 0, CSC = inf and -inf (an asymtote). if COS = 1, CSC = 1.

SOH CAH TOA lol thats geometry

I'm pretty sure its trig.

I'm pretty sure its trig.

sin opp/hyp

cos adj/hyp

tan opp/adj

Yeap, seems like trig to me.//content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif
