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. ...
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...
Answer to: The limit limit h to 0 fraction cos pi + h - -1 h represents f' a for some function f and some number a. Find f x and a. By signing up,...
How does plus-minus((csc^2x-1)/(csc^2x)) equal on of these: secx, cosx, sinx, tanx, cotx, cosx, or 1? Prove the identity. cos(x + y) + cos (x - y) = 2 cos x cos y. Verify the following identity (sec x + csc x)(sin x + cos x) - 2 = tan x + cot x ...
Determine the value of A so that the curve y = 8x + 20 can be written in parametric form as x(t) = t - 3, y(t) = At - 4. Find T, N, and K for the plane curve r(t) = 8 In (sec t)i + 8t j, - \frac {\pi}{2}...
