Find the derivative. y = x^2sin^4 x + x cos^{-2} x Find the derivative:\y=\frac{1}{x^{2.4-\frac{\pi}{\sqrt x}\y=x^{\frac{5}{6 Find the derivative of f (x) = ln ({2 x} / {x + 3}). Find the derivative of y = (tan x)^{ln x} ...
Multiplication signs and parentheses are automatically added, so an entry like2sinxis equivalent to2*sin(x) List of mathematical functions and constants: •ln(x)—natural logarithm •sin(x)—sine •cos(x)—cosine •tan(x)—tangent ...
Diethylstilbestrol is a derivative of stilbene, and it differs from sin-estrol by the presence of a double bond with trans-configuration of the two phenyl groups. In terms of estrogenic activity, this drug surpasses both estrone and hexestrol. Synonyms of this drug are distilben, menopax, ...
A。解析:对于函数\(y = uv\)(这里\(u = x^{2}\),\(v=\sin x\)),根据乘积法则\((uv)^\prime = u^\prime v+uv^\prime\)。\(u = x^{2}\)的导数\(u^\prime = 2x\),\(v=\sin x\)的导数\(v^\prime=\cos x\),所以\(y^\prime = 2x\sin x+x^{2}\cos x\)。选项B中符...
Here you can see the derivative f'(x) and the second derivative f''(x) of some common functions.Notice how the slope of each function is the y-value of the derivative plotted below it.For example, move to where the sin(x) function slope flattens out (slope=0), then see that the...
Pyrrole derivatives were first described by Deidda et al [52] as having fairly potent antimycobacterial activities against several strains of M. tuberculosis. The MICs were between 0.7 and 1.5 μg/mL for the most potent derivative, 1,5-diaryl-2-methyl-3-(4-methylpiperazin-1-yl) methyl-pyrrole...
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 = ...
