Sorry are you commenting because you think there is something wrong with the video. I certainly do make mistakes at times. Please let me know if you think you have spotted one so I can correct it. If you don't respond I plan on removing your comment as it is simply rude with no benefit.

Error in example 1 at 5:46 should be 1.15x10⁸, not 1.54x10⁸ I just read the calculator wrong.

ERROR: In example one I forgot to convert to meters for the wavelength first. The answer should be 6.6 m/s not 660m/s.

ERROR: In the second example I accidentally used the diameter of 100m instead of the radius of 50m.

The original equation is correct, but in my example questions I accidentally flipped the fraction, it should be: k/m not m/k

Not sure why I would be recommended. But I just checked and the thermometer definitely says 23C to start.

I made an error at 9:10 where I factored it into (x-2)(x-2) but the top is unfactorable.

Example 1: I made a calculation error forgetting to square the numbers. I also had a adding for one step then to subtraction. Subtraction was right not adding. Example 2: I flipped final and initial although it doesn't effect the numerical value it will make the answer negative which shows a deacceleration.

I made a mistake and switched sin and cos in my first example! And in the second example I had sin30 instead of sin15! (please look out for the KZbin card to see the mistake!)

@LukasTheBlue 2 жыл бұрын
In the second example I made a mistake substracting 75sin40 instead of adding, it should be adding because it is in the same direction as the normal force! (please look out for the KZbin card to see the mistake!)

in the last question u mistake the -2x^3 for a +2x^3 which changes your final answer to a 8x^3 - 3x when it should be a 4x^3 - 3x

You are totally right, my mistake very late at night haha. Also apparently KZbin has gotten rid of annotation functionality so the most I can do to correct this is have something appear in the top right corner. Hopefully that helps.
