Let f(x)=x^5+x^3+x+1. Then f is one-one on \mathbb{R}. What is f^{-1}(-41)? Which of the following equals {x^2}/{x^3 x^n}? a. x^{n - 1} b. x^{n + 1} c. x^{1 - n} d. 1/{x^n} e. 1/{x^{n + 1 ...
We say "f of x equals x squared"what goes into the function is put inside parentheses () after the name of the function:So f(x) shows us the function is called "f", and "x" goes inAnd we usually see what a function does with the input:...
Tangent in Trigonometry | Definition, Purpose & Examples from Chapter 22 / Lesson 9 16K Read the tangent definition in trigonometry. Learn how to find the tangent of a triangle and what is the tangent of an angle. Using examples, understand how to use the tangent to find the side, and...
which equals . Meanwhile, the second expression can be rearranged as By (2), (3) we can simplify and so the inner product is , leading to the “five part rule” In the case of a right-angled triangle , this simplifies to one of Napier’s rules which in the infinitesimal limit...
: An isosceles triangle plus an edge incident to the apex, and whose length equals the length of the base. (See Figure 1 and Lemma 1 of Dumitrescu’s paper.) So the question is asking whether if an point set avoids all of these patterns , then it must generate distances. Given tha...
The given equation of the curve is y = 2x2+ 3x + 1. The aim is to find the slope of the tangent at the given point and hence we need to differentiate the equation. d/dx (y) = d/dx (2x2+ 3x + 1) dy/dx = 4x + 3 ...

of dipis the ratio of the vertical component of earth's magnetic field to the horizontal component of earth's magnetic field. Since, the horizontal and vertical components of earth's magnetic field are equal, their ratio equals one. Then the angle of dip will be the inverse tangent of one...
How to Calculate Centripetal Force The mathematical representation of centripetal force was derived by Dutch physicist Christiaan Huygens in 1659. For a body following a circular path at constant speed, the radius of the circle (r) equals the mass of the body (m) times the square ofthe velocit...
