I havs a math question;
The line y = mx+b is a tangent to the elipse at X^2/9+Y^2/4=1
Show that b^2=9M^2+4
I know you can do this using the discriminate and a shit load of algebra, but is there a way to do it via equation the coefficients of a general tangent of an elipse to y=mx+b?
Hey,
so im having trouble with understanding verticle acceleration, question say to take g=10 or some other positive number. What i dont get is how can g be a positive number, if it was the object would be moving up and never fall.
Why dont they tell us g is negative instead of having us...
Hey, I just had a Math exam and I got efed up
If you know a particle is in SMH, Is it's center of origin when t=0?
if it helps the equation was 2cos(t+pi/4)
Thanks in advance :)
It depends on the individual, and i dont take chem :3
but, with physics there's a lot you need to take on faith, purley due to the shitty syllabus which really screws with your head
Hey all,
