I'm a high school maths teacher in NSW, Australia. I make videos for my students, so all videos have been made with them in mind. My videos explain maths concepts - covering a range of topics from Year 7 maths to the NSW Year 12 Mathematics Standard, Advanced and Extension 1 courses.
Hi, nice video. I want to calculate o erro between 2 sensors. S1 is a reference sensor and S2 is a new sensor. Porcentual error could be calculate as Erro(%)=abs(S1-S2)/S1*100 ?
Heather you are BRILLIANT. I love all your incredible instructional videos....very clear and concise...easy to follow/understand. Keep them coming please.
So I am curious, I am trying to help my son, when punching it in on a calculator and google, I get : Sin 40 = 0.745 Sin140 = 0.980, Cos 70= 0.633 cos 110 =-0.999, tan15 = -0.856 Tan165 = -15.041 Are we calculating incorrectly?
Ok probability calculation but these calculations are not useful. The useful thing is to understand combinations and permutations. Where are going to use your probability values that you calculated.. No where at all. If it is a problem of discrete random process ,your probability calculations is nowhere to use. Calculate lottery number probabity with getting 6 numbers right in most economical way for people!
Okey I'm only just getting started at this so don't judge : why does one not mirror the half rectangle through the line and then divide the result by two ? Like the line goes through point a and b, assuming that the images are positive, even if the distances of ya and yb from the x axis are different, one can always draw a rectangle of hight (ya+yb) and of width (xb-xa) and no matter how squiggly the curve of the function, if the rectangle is mirrored than the area of each half of the rectangle is going to be half of the area of the full rectangle right ?
