WebNow, let us sketch the derivative of cosx.First, plot the graph of cosx over the closed interval [0;2… Again, we need to find the critical points of cosx.There are three critical points on this interval: at x = 0, x = …, and x = 2….So the graph of the derivative of cosx touches the x-axis on this interval at three points: (0;0), (…;0), and (2…;0).). Now we … Webx=sqrt (y) dy/dx (x^2)=2x so 2x=2sqrt (y) To know dy/dx at any point we just substitute. For example, X: dy/dx at (0.5 , 0.25) = 2 * 0.5=1 Y: dy/dx = 2 * sqrt (0.25) = 1 It seems OK, but remember: this is Parabola, so we have 2 points at Y = 0.25. And the derivative of one is (1), the derivative of other (-1) so we have 2 X for each Y.
WebDerivatives of Tangent, Cotangent, Secant, and Cosecant We can get the derivatives of the other four trig functions by applying the quotient rule to sine and cosine. For instance, d d x ( tan ( x)) = ( sin ( x) cos ( x)) ′ = cos ( x) ( sin ( x)) ′ − sin ( x) ( cos ( x)) ′ cos 2 ( x) = cos 2 ( x) + sin 2 ( x) cos 2 ( x) = 1 cos 2 ( x) = sec 2 ( x).
