Differentiation MCQ : Here you will find MCQ Questions related to "Differentiation" in Matlab. These Differentiation MCQ Questions Will help you to improve your Matlab knowledge and will prepare you for various Examinations like Competitive Exams, Placements, Interviews and other Entrance Exmaniations.
MATLAB provides the __________ command for computing symbolic derivatives.
D. None of the above
Explanation: MATLAB provides the diff command for computing symbolic derivatives. In its simplest form, you pass the function you want to differentiate to diff command as an argument.
Which of the following is first order derivative ?
Explanation: f'(x) for a first order derivative and f"(x) for a second order derivative.
To compute higher derivatives of a function f, we use the syntax ?
Explanation: To compute higher derivatives of a function f, we use the syntax diff(f,n).
For a function y = f(x) the points on the graph where the graph has zero slope are called?
A. graphical points
B. locality points
C. differential points
D. stationary points
Explanation: For a function y = f(x) the points on the graph where the graph has zero slope are called stationary points.
Which rule does MATLAB use while differentiating a set of functions?
A. u-v rule
B. by parts
C. no pre-defined rule
D. not possible
Explanation: If we give an argument within our command diff() which is a product of multiple functions or division of two functions; we will get the result that will be generated according to the u-v rule. This makes MATLAB very versatile for the applications concerning differentiation.
The output for diff(p2,q) is _______
B. 2 dp/dq
Explanation: We are differentiating the function p^2 with respect to q. Hence the value will be 0. The 2nd argument in the diff() command is the variable, with respect to which- we differentiate our function.
While solving a differential equation, MATLAB will show us the ___________
A. General Solution
B. Particular Solution
C. Complementary function
D. Depends on the equation
Explanation: When we use dsolve to find the solution of an ordinary differential equation, we get the general solution of the equation. Now, this equation comprises of both the complementary function and the particular integral for the general solution. Hence, it is not that we only get the particular integral as a solution after using dsolve().
stationary points are where f'(x) =?
Explanation: stationary points are where f'(x) = 0.
The method of differentiation in MATLAB is pertinent for getting __________
A. Higher order differential equations
B. Lower order differential equations
C. A certain ordered differential equation, within a range
D. Any order differential equation
Explanation: MATLAB cannot find unnecessarily high ordered differential equation. It will compute a differential equation but the order of the differential equation is limited.
MATLAB provides the dsolve command for solving differential equations symbolically.
C. Can be true or false
D. Can not say
Explanation: True, MATLAB provides the dsolve command for solving differential equations symbolically.
