(In other words the derivative of x3is 3x2) So it is simply this: "multiply by power then reduce power by 1" It can also be used in cases like this: Example: What isddx(1/x) ? 1/x is alsox-1 We can use the Power Rule, where n = −1: ...
Next step optimization of NBD compounds was based on an additional suggestion coming from an analysis of X-ray crystallographic complexes. In fact, the alcoholic side chain of 9 in its complex with gp120 (entry 5u6e of the protein data bank, Table 2) was not involved in any interaction wi...
derivativethe change of a function, f(x), with respect to an infinitesimally small change in the independent variable,x; the limit of [f(a+ Δx)–f(a)]/Δx, atx=a, as the increment, Δx, tends to 0. Symbols: df(x)/dx, f′(x), Df(x):the derivative of xnis nxn–1 ...
A range of bicyclic phosphates (154; X = Y = O) have been the subject of biological assessment 〈82ABC411〉, and a 1-hydroxmethyl derivative (154; X = Y = O; R = HOCH2) has been patented for its herbicidal properties 〈66USP3287448〉. The effects of various drug pretreatments on...

PURPOSE: To provide the subject new 1,2,5-thiadiazole derivatives useful as an organic intermediate or an intermediate for synthesis of a medical and agricultural drug and to provide a production method capable of synthesizing them from readily available raw materials in high yields and of readily...
THE DERIVATIVE of sin x is cos x. To prove that, we will use the following identity:sin A − sin B = 2 cos ½(A + B) sin ½(A − B).(Topic 20 of Trigonometry.)Problem 1. Use that identity to show:sin (x + h) − sin x = ...
In order to solve this question, we will first start by considering $y=\arctan x$. It is the same as $y={{\tan }^{-1}}x$. Now let us move the inverse tangent to the left side of the equation. By doing so, it will give us, ...
