Derivative of cos 4theta
WebI am confused why evaluating the derivative of the polar expression--r' (theta) = 2 cos (2 theta)) -- at pi/4 equals zero, while the dy/dt / dx/dt evaluation of r (theta)=sin (2theta) equals negative 1. Its seems like the dy/dt / dx/dt derivative of the initial expression should equal xy expression of the polar derivative! • ( 2 votes) Upvote WebProving that the derivative of sin(x) is cos(x) and that the derivative of cos(x) is -sin(x). The trigonometric functions sin ( x ) \sin(x) sin ( x ) sine, left parenthesis, x, right parenthesis and cos ( x ) \cos(x) cos ( x ) cosine, left parenthesis, x, right parenthesis play a …

WebJun 16, 2024 · 1. If θ is just a constant (meaning that x and θ are independent variables), then : cos x θ = ( cos θ) x = e x ln ( cos θ) and thus ( cos x θ) ′ = ( e x ln ( cos θ)) ′ = ( x ln ( cos θ)) ′ ⋅ e x ln ( cos θ) = ln ( cos θ) e x ln ( cos θ) = ln ( … WebOct 7, 2008 · Knowing that derivative of sinx is cosx and derivative of cosx is -senx, prove by induction, that the 2n derivative of sinx = ((- 1) ^ n ) * sinx and the 2n derivative of cosx = ((- 1) ^ n)* cosx. I wanted to confirm that I solved these problems correctly (we had to convert the polar curves to Cartesian equations).

So, we will write −sin(x) but keep the inside function intact, giving us a −sin(πx). We then multiply that by the derivative of πx, which is just π, giving the full derivative of −πsin(πx).
