[1 point for description of both types of bifurcations] d) For saddle node bifurcations f(x) = 0 and f'(x) = 0 ⇒ r = sin(x) x and r = cos(x). Since r 1 ⇒ ... Notice that S(x) sin kx is even (equal integrals from −π to 0 and from 0 to π). I will go immediately to the most important example of a Fourier sine series. S( ... Jan 23, 2023 ... For the cosines, as with the sines, a more compact way to write the zeroes of the function is just ½π+nπ, or (n+½)π, because n can be negative. sin x is known as a periodic function that oscillates at regular intervals. Sine function crosses the x-axis at x = 0,π, and 2π in the domain. Since x0 was arbitrarily chosen hence the function f(x) is continuous in R. Each fk(x) = sin(x/k) k is differentiable with. The mean value theorem states there is at least one point in the interval (m, k) with tangent line parallel to the secant line between m and k. You should be able to find local zeros using the bracketed root function: root(x*cos(x)-sin(x),-1,1)= root(x*cos(x)-sin(x),-5,-4)= etc. Success! cos x dx + C = −x cos x + sin x + C so the general solution is y = − cos x ...

This means we are looking for all the ...
