i know that
shut up leghorin
if i did that
it would create literal hel
It has been a while since I have done trig proofs
what im saying
give me a min
is
wait just tell me if this is right
multiply bottem by conjugate
I am thinking about that
gets me cos^2(x/2) - sin^2(x/2)
which i can bring out the double angle identity
cos2(x/2)
or just cosx
wait
does that work?
is this x/2 or 1/2z
1/2x
(1/2)(x)
I was about to say
okay
1 sec
OH WAIT
I THINK IT WORKS
I ended up with 1-2sin^2(x/2) on the bottom
seems likely
cause top would be cos^2(x/2) + sin^2(x/2) + 2sin(x/2)cos(x/2)
which would be 1+2sin(x/2)cos(x/2)
yeah
there you go
which is 1 + sin2(x/2)
so 1 + sin / cos
or secx + tanx
alright
yeah
Follow up question for leg
have you ever used an oscilloscope
and is it difficult to use
I have a lab tomorrow
seems to be just a bunch of voltage messurements
oh, have any of you worked with human performance and feet?
I figured
no clue what that is
anyone have experience with an arch height index measurement system?
