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