In this lesson we talk about while loops, how they work and how to code it in PHP. We use a while loop to set up a compound interest calculator.
A subscriber found an alternative solution to the previous trigonometry calculus problem using pythagoras and similar triangles. Have a look!
In this tutorial we talk about the if statement as well as comparison operators. We also talk about else and elseif statements to be used in conjunction with the if statement.
This is one of the hardest questions you will ever do that involves the derivative of trigonometric functions and finding the maximum / minimum. Have fun with it!
So in this tutorial I show you how to get one NXT brick to communicate to another NXT brick via Bluetooth. To be more specific, I rotate a motor on the first NXT brick and this results in the motor on the other NXT brick to rotate. So effectively you could use one NXT brick …
This is a problem solving question for differentiation in calculus – how to find the maximum volume of a cylinder inscribed in a cone. You must know how to find maximum and minimum of a function before attempting this question.
I challenge you to program a robot that measures your height! Here is how I’ve done it. Comment once you have completed my challenge! I’ll make the solutions tutorial video soon.
Thanks to a subscriber for asking this question. This is a differentiation practice question for calculus that involves finding the second derivative of a function. You will need to understand the chain rule and the product rule before attempting this question. Have fun 🙂
This is actually mission 6 in the original activity but I decided to do it third, because the programming is pretty simple. In this video I show you how to program the robot.
This is a question that involves chain rule, hyperbolas (reciprocal functions) and limits. Try it yourself first then have a look at the answer 🙂
