To find the equation of the tangent line to the curve y = 2x² - 4x + 3, we have to differentiate. Taking each part of the equation separately, we can calculate dy/dx = 4x - 4. By differentiatin...

y = 1/x^2 is the same asy = x^-2 , now we can use the standard differentiation formula nx^n-1 to gety = -2x^-3y = -2/x^3

Empirical formula is the simplest whole number ratio of atoms of each element in a compound. With the empirical formula and relative molecular mass, we can determine the actual molecular formula of a comp...

The derivative of distance with respect to time is velocity.

This is a typical question for a Core 1 paper. (a) integral of y = (-2)x^(-1/2) + 0.1x^5 + 2x +C Method: Increase the power of x by +1, divide the term through by the new power. (b) dy/dx = (-3/2)x^(-5/2)...
