Derivative of sin x commencer à apprendre		cos x
Derivative of cos x commencer à apprendre		- sin x
Derivative of tan x commencer à apprendre		1/((cos x)^2)
Derivative of e^x commencer à apprendre		e^x
Derivative of ln x commencer à apprendre		1/x
Product Rule commencer à apprendre		y = uv -> dy/dx = u(dv/dx) + v(du/dx)
Chain rule commencer à apprendre		y = g(u), u=f(x) -> dy/dx = dy/du * du/dx
x^(-1/2) equals to: commencer à apprendre		1/(x^(1/2))
Quotient Rule commencer à apprendre		y=u/v -> dy/dx = (v(du/dx) - u(dv/dx))/v^2
To find a gradient of the curve at some point x commencer à apprendre		Derivative a function and apply needed x value to the derivative equation
To find tangent of f(x) when x = something commencer à apprendre		1. Calculate gradient at that point by derivative 2. Use the equation y=mx+c at that point to find the c value
What is Normal line of the curve at some point commencer à apprendre		It is the line perpendicular to the tangent line at that point
The slope of the normal commencer à apprendre		Its the number opposite and reciprocal (l. odwrotna) to the tangent slope
