The derivative of a function is the limit of the ratio between the variation of the function {eq}\Delta f(x) {/eq}, and the variation of the independent variable {eq}\Delta x {/eq}, as {eq}\Delta x\to 0 {/eq}. Writing t...
Consider the parametric curve: x = 10 cos theta, y = 6 sin theta, - pi/2 less than or equal to theta less than or equal to pi/2 The curve is (part of) an ellipse and the cartesian equation has the form x^2/a^2 + y^2/...

ORP5 and ORP8 have previously been shown to counter-exchange PS with the PM phosphoinositides PI4P and PIP2 at ER-PM contact sites in HeLa cells (Chung et al., 2015; Ghai et al., 2017). However, PI4P and PIP2 are not present on the mitochondrial membranes, while PE is highly abund...
Simplify :\tan^{2}x - \sin^{2}x Simplify the trigonometric expression \dfrac{sec(x) + csc(x)}{1+ tan(x)} by writing the simplified form in terms of sin(x). Simplify: (sin x + x cos x)x cos x - x sin x (cos x -x sin x) / (x cos x)^2. ...
