WebJun 9, 2016 · 1-tan^2 (x) = 1 - (sin 2 x)/ (cos 2 x) = [cos 2 x - sin 2 x]/cos 2 x = [cos 2x]/cos 2 x is a posibly 'simplified' version in that it has been boiled down to only cosines. Simplify has a particular meaning in mathematics: to rewrite with as few symbols as possible. Mark, I made a credible try to find an equivalent expression, and attempted to ... WebTake the inverse tangent of both sides of the equation to extract θ θ from inside the tangent. θ = arctan(−1) θ = arctan ( - 1) Simplify the right side. Tap for more steps... θ = − π 4 θ = - π 4 The tangent function is negative in the second and fourth quadrants.

Webquadrant 2 has x negative now, since it is on the left of the y axis. if it's easier you can remember x = 1 is on the right of the y axis, and x = -1 is on the left. at 180 degres, or pi radians we are at the x axis again, but on the negative side. again, y is 0 but x is negative rather than an angle of 0. WebExample 1: Finding the equation of the line tangent to the graph of f (x)=x^2 f (x) = x2 at x=3 x = 3 Step 1 What's an expression for the derivative of f (x)=x^2 f (x) = x2 at x=3 x = 3? … ridgeville ca weather
