WebApr 12, 2024 · fx + fv * t + 1/2 * a * t^2 = tx + tv * t. The first equation is basically "followers velocity plus acceleration times time equals target velocity". The second one is "give the followers initial position, time, and deceleration, move as far as the targets starting position plus the time and velocity of the target." WebEnter the equation/congruence, the variables and the value of the modulo. The value of the modulo is global and applies to all equations. Example: x+12≡ 3 mod 5 ⇒x =1 x + 12 ≡ 3 mod 5 ⇒ x = 1. The modular equation solver can not work with inequalities, only the equal sign is accepted to solve the equations.

An example is also provided to explain … WebThe congruence we write in the equivalent way: 7 x – 5 y = 3. The one particular solution to the equation above is $x_0 = 2, y_0 = -3$, so $7x_0 – 5y_0 = 3$ is valid. By subtracting the obtained equations we obtain 7 ( x – x 0) – 5 ( y – y 0) = 0. It follows x – x 0 = 5 t 1, k 1 ∈ Z, that is, x = 2 + 5 k 1, k 1 ∈ Z.
