f (x) = tan(x) Using the limit definition of the derivative, which states that the derivative of f (x) is given by f '(x) = lim Δx→0 f (x + Δx) − f (x) Δx, we have: f '(x) = lim Δx→0 tan(x +Δx) −tan(x) Δx …

you need to derive f(x) and then you can have the linear approximation of this function with the formula y = f(a) + f'(a)(x-a)

Dec 16, 2017 · Point P (-10,14) is a point external to a circle. Points A (5,6), B (x,y), C (1,4) are on the circle. Line PC is tangent to circle and P, A, and B are collinear, with B between P and A. …

Dec 24, 2015 · Let chord CD is parallel to tangent to circle at point A as shown in figure CD = 2, ∠CAD= Π/3, then area of ΔCAD is ? (A) √3 (B) 4√3 (C) 16√3 (D) 4 Geometry

Dec 15, 2016 · |x| = √x2 This is a one dimensional version of the distance formula. So: y = √(x2 −9)2 +√(x4 −16)2 +√(x6 −1)2 graph {y = sqrt ( (x^2-9)^2)+sqrt ( (x^4-16)^2)+sqrt ( (x^6-1)^2) [ …

If a line is tangent to a circle, then it is perpendicular to the radius drawn to the point of tangency. The parametric equations of a curve are x=#t^2# and y=#3/t#. Points P and Q with parameters …
