  2. How do I linearize a square root graph? - Physics Forums

    www.physicsforums.com/threads/how-do-i-linearize-a-square-root-graph.772635

    To linearize a square root graph, use the equation y = mx + b, where m is the slope and b is the y-intercept. To find the slope, calculate the rise over run. To find the y-intercept, use the equation or find the point where the line crosses the y-axis on a graph. Any square root graph can be linearized, but the resulting graph may not be an ...

  3. Is the Square Root of 0 Undefined? - Physics Forums

    www.physicsforums.com/threads/is-the-square-root-of-0-undefined.49379

    In summary, the square root of 0 is undefined in the real numbers because the limit of the function does not exist at x = 0. However, when considering a complex square root function, the limit does exist and the function is continuous at x = 0. The use of the imaginary number i to disprove the existence of the limit is a red herring, as the ...

  4. Is sqrt(x) a function if it includes both positive and negative...

    www.physicsforums.com/threads/is-sqrt-x-a-function-if-it-includes-both...

    Yes, sqrt (x) can be made into a function if we restrict the domain to only include non-negative numbers. This means that the input can only be values greater than or equal to 0, and the corresponding output would be the positive square root. This would then satisfy the definition of a function. 4.

  5. Proof: x is irrational => sqrt(x) is irrational - Physics Forums

    www.physicsforums.com/threads/proof-x-is-irrational-sqrt-x-is-irrational.86799

    If x is irrational, then its square root, sqrt (x), must also be irrational because sqrt (x) cannot be expressed as a fraction of two integers, just like x. 4. Can a number be both rational and irrational? No, a number cannot be both rational and irrational. By definition, a number is either rational or irrational.

  6. Why is the square root of x^2 = |x|? - Physics Forums

    www.physicsforums.com/threads/why-is-the-square-root-of-x-2-x.1057005

    But definitionally, the square root function is the positive answer to the question of what number squared is x^2. The quadratic formula gives the +/- outside of the square root function. Your confusion is between the answer to what number squared is 1 and what is the square root of 1. The square root is 1.

  7. What is the square root of x^2? - Physics Forums

    www.physicsforums.com/threads/what-is-the-square-root-of-x-2.648287

    The square root function (√) is defined (usually) to return the principal square root, i.e. the non-negative one. But the "square root" of x 2 has two possible values: ±√(x 2) = ±|x| = ±x. As for (x 2) 0.5, I would say that does not define a function in the strict sense, so it returns a ± result. Prepared to be shouted down on that one ...

  8. Derivative of Square Root of x at 0 - Physics Forums

    www.physicsforums.com/threads/derivative-of-square-root-of-x-at-0.1012632

    The derivative of the square root of x at 0 is calculated using the power rule for derivatives, which states that the derivative of x^n is equal to n*x^ (n-1). In this case, n=1/2, so the derivative is equal to (1/2)*x^ (-1/2), which simplifies to 1/2x^ (-1/2) or 1/2x^ (1/2). 3. Why is the derivative of the square root of x at 0 equal to 1/2 ...

  9. Maclaurin series for square root (1+x) - Physics Forums

    www.physicsforums.com/threads/maclaurin-series-for-square-root-1-x.386545

    A Maclaurin series for square root (1+x) is a mathematical representation of the square root function using a specific type of series expansion called a Maclaurin series. It is a way to approximate the square root of a number that is close to 1, by using an infinite sum of terms involving powers of x. 2.

  10. How Does Omega Squared Equal k/m in Simple Harmonic Motion?

    www.physicsforums.com/threads/how-does-omega-squared-equal-k-m-in-simple...

    The equation ω² = k/m can be derived from the equation for the period of oscillations of a mass on a spring, which is T = 2π√ (m/k). By squaring both sides and rearranging, we get ω² = k/m. This equation shows the relationship between the angular frequency (ω) and the spring constant (k) and mass (m). 4.

  11. R= the square root of x^2 + y^2 - Physics Forums

    www.physicsforums.com/threads/r-the-square-root-of-x-2-y-2.184440

    To find the length of the displacement vector, we can use the Pythagorean theorem. The length of the displacement vector, R, is equal to the square root of the sum of the squares of its components. In this case, R = √ (3854.9^2 + 2436.6^2 + 2085^2) = 5556.9 m. In conclusion, the x, y, and z components of the displacement vector from the base ...
