If the equation is of the form y = f(x) where f is some function of the variable x, then
The initial value is found by evaluation f(0): that is, the value of f(x) when x = 0.
The rate of change is the derivative of f(x) with respect to x, written as f'(x). That is the limit (if it exists), as dx tends to 0, of [f(x+dx) - f(x)]/dx.
In the simple case, where f(x) is a linear equation of the form y = mx + c, then f(0) = c and f'(x) = m
Gradient (on a graph as I assume you mean), or the differential of the line's equation (dy/dx which means "the difference in y with respect to a difference in x").
Acceleration equals the change in the velocity divided by time. The change in the velocity is found by subtracting the initial velocity from the final velocity. It is written as "a equals delta v over t."
The answer depends on what information you are given - and in what form. If the equation of the curve is given in polar coordinates or in parametric form, the process is quite different to that required when given the Cartesian equation.
Acceleration=force divided by mass. The above is Newtons second law. Acceleration is also the change in velocity over the change in time, so it can also be stated as a=(final velocity - initial velocity)/(elapsed time)
To find the constant rate of change is by taking the final minus initial over the initial.
To calculate the initial rate of reaction from concentration, you can use the rate equation. This equation relates the rate of reaction to the concentrations of the reactants. By measuring the change in concentration of the reactants over a short period of time at the beginning of the reaction, you can determine the initial rate of reaction.
To determine the change in an object's momentum, you need to know the initial momentum of the object (mass x initial velocity) and the final momentum of the object (mass x final velocity). The change in momentum is equal to the final momentum minus the initial momentum.
To determine the initial rate of reaction from a table, you can look at the change in concentration of reactants over time. By calculating the slope of the initial linear portion of the concentration vs. time graph, you can find the initial rate of reaction.
The derivative of a quadratic function is always linear (e.g. the rate of change of a quadratic increases or decreases linearly).
To find the change in momentum of an object, you can use the formula: Change in Momentum Final Momentum - Initial Momentum. This involves subtracting the initial momentum of the object from its final momentum to determine how much the momentum has changed.
To determine the change in temperature, you can subtract the initial temperature from the final temperature. This will give you the difference in temperature, showing how much the temperature has changed.
The equation for linear acceleration is a (vf - vi) / t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time. This equation is used to calculate the rate of change in velocity of an object by finding the difference between the final and initial velocities, and dividing that by the time taken for the change to occur.
accelaration is defined as the rate of change of velocity. Therefore the formula for acceleration is a =(Final Velocity - Initial Velocity) divide by the (change in time)
Acceleration is calculated using the equation a = (v_f - v_i) / t, where a is the acceleration, v_f is the final velocity, v_i is the initial velocity, and t is the time taken to change from the initial velocity to the final velocity.
To determine the change in volume, you can use the ideal gas law equation: V2 = V1*(T2/T1). Substituting the values, the change in volume would be V2 - V1 = V1*(T2/T1) - V1. Just plug in the initial volume of 1.95 L, initial temperature of 250.0 K, and final temperature of 442.2 K to find the change in volume.
Delta in the equation for thermal energy typically represents a change or difference, such as a change in temperature or heat energy. It signifies the final state of the system minus the initial state to calculate the thermal energy change.
Acceleration is defined as the rate of change of velocity with respect to time. The equation for acceleration is a = (v_f - v_i) / t, where a is acceleration, v_f is the final velocity, v_i is the initial velocity, and t is the time interval.
