The corresponding "slope" is zero when the imaginary component vanishes; namely, at odd multiples of π / 2, as expected. – Blue Aug 8, 2024 at 12:13 1 @Blue you could repost that comment as an answer. – Mark S.

WebMar 29, 2015 · 2 Answers. Sorted by: 1. I assume you can exchange partial derivatives, so that: ∂ ∂ θ ∂ z ∂ x = ∂ ∂ x ∂ z ∂ θ. Then you can use your answer form part (i) to plug into ∂ z ∂ θ, and take the partial of that with respect to x. Share. WebSep 24, 2024 · I am a high school student and am reading derivatives for the first time. In my book , before the topic of derivatives of trigonometric functions we were given a relationship between $\cos \theta$ and $\sin \theta$ which was : $\cos \theta$ $< \frac{\sin \theta}{\theta}$; $ 0 < \theta < \frac{π}{2}$, $\frac{-π}{2} < \theta< 0$ When I reached … diane enright taos realtor

WebNov 16, 2024 · With directional derivatives we can now ask how a function is changing if we allow all the independent variables to change rather than holding all but one constant as we had to do with partial derivatives. In addition, we will define the gradient vector to help with some of the notation and work here. ... where \(\theta \) is the angle between ...
