Check Chain Rule
The chain rule handles functions nested inside other functions by multiplying the outer derivative by the inner derivative.
Formula: d/dx f(g(x)) = fβ²(g(x))gβ²(x)
Calculus results depend on the function and the conditions around it. A limit, derivative, or integral should therefore be read together with its point or bounds.
The stated formula is a compact audit of what the calculator is evaluating, which makes it easier to check the output independently.
