start learning

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