Using trigonometric identity to derive the derivative of a trigonometric function:For trigonometric functions, the derivative of these functions is based on the derivatives of the sine and cosine functions. Therefore, to determine the derivative of other trigonometric functions, knowledge of trigonometric ...

Proof. — It follows from Jacobi's formula for the derivative of the determinant, and (3.27) that ∂ det( ∂x ∂ det( ∂y +,1(x, y, λ), +,1(x, y, λ), −,2(x, y, λ)) = (tr A) det( +,1(x, y, λ), −,2(x, y, λ)) −,2(x, y, λ)) =...
Mitochondria from many eukaryotic clades take up large amounts of calcium (Ca2+) via an inner membrane transporter called the uniporter. Transport by the uniporter is membrane potential dependent and sensitive to ruthenium red or its derivative Ru360 (ref. 1). Electrophysiological studies have shown...
