WebJul 12, 2024 · I have used the following code to plot x=linspace(-90,90,10000); y=sin(x)./x; plot(x,y); axis([-90 90 -1.5 1.5]) xlabel('x') ylabel('y') title('A GRAPH OF A FUNCTION ... Web1. You ask why the graph of sin looks as it is on [ 0, π / 2]. You can easily (with the help of some trig formulas) calculate the values of sin x for x = 0, π / 6, π / 3, π / 4, π / 2, π / 12, π / 5. Plot these values. Keep in mind that sin is continuous as a ratio of two continuous functions (opposite side/hypothenuse). truck box bins

Web5 years ago. Sal was trying to prove that the limit of sin x/x as x approaches zero. To prove this, we'd need to consider values of x approaching 0 from both the positive and the negative side. So, for the sake of simplicity, he cares about the values of x approaching 0 in the interval (-pi/2, pi/2), which approach 0 from both the negative (-pi ... WebThe graph of \(y=\sin\space x\) is symmetric about the origin, because it is an odd function. The graph of \(y=\cos\space x\) is symmetric across the \(y\)-axis, because it is an even function.
