I am very pleased to inform you that we are taking another step forward in eTrapez.
We have created an application thanks to which you can learn to calculate derivatives in a completely new way.
The principle is very simple: you solve the derivative from our Homework as before, with the difference that you enter the next steps not on a piece of paper with a pen, but in a computer browser.
Our application checks the correctness of each of your entered transitions, and also verifies the final result.
Example 1
Let’s take the derivative of y = \ln \left( {\frac{{5x - 1)){{3x + 2))} \right) in our application. This is example 19 from the Homework for Lesson 2 of the Course Derivatives and the Study of Variation of Functions .
We choose the appropriate example from the list:
We introduce the first step (let’s say the correct one):
We go further (I’m getting confused now):
We correct ourselves, in the formula for the derivative of the quotient, the numerator should of course be minus:
We solve calmly further, in addition to counting the derivatives in the numerator, we also cross shorten:
And the next step, now just tidying up:
Let’s make another mistake, okay?
Corrected, it should of course be like this:
It just so happens that this is the final result and there is nothing to count on 🙂
Example 2 (VIDEO)
Where can I access the application?
The application is available as an addition to the Courses:
- Course Derivatives and Studying the Course of Variation of Functions (studies)
- Extended Matura (high school) course
- Trigonometry course (high school)
And in Bundles containing these Courses:
Price
The application is available as part of a monthly subscription, at PLN 4.99 / month .
I heartily recommend and invite you
