WebThen, for x ∈(−1,1), (f−1)′(x)= 1 cos(f−1(x)). Suppose that x ∈(0,1) and let α = f−1(x). Consider the right triangle with the hypothenuse of the length 1 and an angle measured α radians. The length of the leg opposite to the angle α equals sinα= x which implies d dx(sin−1x)= 1 √1−x2. Web1. first step on the right hand side should be 3 x + 5 not 3 x + 4. Then proceeding the same way: 4 ( x 2 − x − 6) = x 2 + 12 x + 36 3 x 2 − 16 x − 60 = 0. Since the discriminant of that equation is 16 2 − 4 ⋅ 3 ⋅ 60 < 0 there are no solutions. UPDATE you changed the problem now, so you get 4 ( x 2 − x − 6) = x 2 + 10 x + 25 ...

Web5 Jun 2024 · One should be careful with simplifications and with squaring. For instance, the equation x = 1 has just one solution, but x 2 = 1 2 has two. Since x = ( x) 2, you can set y = x and try to solve y y 2 + 3 = a with the limitation that … WebLaTeX2e: An unofficial reference manual 1 About this document 2 Overview of LaTeX 3 Document classes 4 Fonts 5 Layout 6 Sectioning 7 Cross references 8 Environments 9 Line breakin

WebImagine this: There's an equation x = 2. Right now, x is only equal to two. Square both sides, and x^2 = 4. For some reason, if you want to take the square root of both sides, and you get x= +/- 2, because -2 squared is still equal to four. But, according to …
