Give your answer in the form y = f (x). This is a question taken from a core 4 paper and is a typical example of a differential equation question. The first thing to notice about this equation is that it is "separable", meaning we can rearrange it to get The curve C has equation x^2 – 3xy – 4y^2 + 64 = 0; find dy/dx in terms of x and y, and thus find the coordinates of the points on C where dy/dx = 0 if y esinx tan x x prove that dy dx esin x cos x tan x x 2x cosec 2x log tan x - Mathematics - TopperLearning.com | ge8jt3uu The differentiation of a function f(x) is represented as f’(x). If f(x) = y, then f’(x) = dy/dx, which means y is differentiated with respect to x. Before we start solving some questions based on differentiation, let us see the general differentiation formulas used here. y = tan^-1(sec x + tan x) => tan y = sec x + tan x Differentiating both sides w.r.t. x sec^2 y * dy/dx = sec x * tan x + sec^2 x => dy/dx = sec x (tan x + sec x Find the area of the region bounded by y 2 = 9x, x = 2, x = 4 and the x-axis in the first quadrant.

It's just that D is the simplified answer of C. ∫tan(x) dx, can be solved using a simple u-substitution where: u = cos(x) -du = sin(x) dx So that will therefore give us: -∫du / u *Let "[" be the absolute value sign* Integrating with respect to u gives us: -ln[u] + C Substituting
