It absolutely pains me to know videos as informative as this have 79k views and videos of people showing zero talent dancing to viral sound bites have millions.
This channel is probably the most underrated one on RU-vid. Like this channel has actually saved my life an hundreds of occasions. Like If you don’t understand anything from physics, chemistry, biology or maths, come here and search for your topic here. I guarantee you that it’s somewhere in this channel. Their videos have saved me soo much and the videos are done so well and clearly. Thank you again cognito!
Hi cognito alot of students are benefiting from these amazing videos. Is there any chance you'll be doing a-level science videos as alot of people would benefit from it
Very clear, and nicely presented. I've read a few 'text book' explanations, but could never understand or remember any of them! But your audio/visual tuition made it easy to remember. I never knew it was so simple!!! Many thanks! (*_*)
Great video! And I would like to say that I'm a frequent user of you website, and I have a suggestion. I think releasing a mobile app version of the website in the playstore would be a massive hit! As its kind of hard to view website in mobile phones and apps are rather easily accessible in that case. Its only a suggestion. I'm writing my GCSEs next May/June. And I'll make sure to put all my results soon as I get them, Best wishes Amadeus and Tom.
I joined cognito over a year ago. Its been very helpfull but recently they made some stuff for money. But the free stuff are still very helpful. Go check it out. You can thank me later 😉
Your explanation made this lesson so easy to understand. Thank you to all at Cognito for never failing to help us with all the complicated theories of Maths : )))
i don't understand how in 2:30 you got 3 can please explain more on that cause the root of 27 cant be turned in to a normal number like root 81 wich = 9 so i am confused
its the cube root of 27 so, 3 x 3 x 3 = 27 or cube root of 27 = 3. with 81, you do the root but to the power of 4 this time so the answer would be 3 x 3 x 3 x 3 = 81
