👍🏻❤️

Kia grade aya?

@@FireBoy-qn4jsAray bhai itna purana comment😂😂. A* aya tha Alhumdulliallah brother. Iss banday ki videos bahut achi hai bas dake kr practice krtay raho inshallah apka bhi aye ga🤝. Best of luck

@nazeerahmad8169 thanks 😊 30 ko paper ha I will try my best 💘

i can relate

@@affanqamer9598 best of luck for tomorrows paper man😭

​@@hirafatima3456 What grade did you get

watch mathlete,a chennel on youtube

try 'Zaineatics'

you can use any formula when you are getting the same or correct answer

Usually, to find min point, you can complete squares for the quadratic equation. And yes, it works for all quadratics equations

@@OALevelMathematics thank you so much I found the formula -b/2@

When you have the equation of the line: y = 2x - 2, it is easy to find passing points. In the video. I assume X = 0 (replace x = 0 in the equation), Y will be -2. So that gives me Point (0, -2) Then, I assumed Y = 0 (replace y = 0 in the equation), X will be 1, so that gives me Point (1, 0) So now I can draw my line on the graph.

@@OALevelMathematics that makes so much more sense omg thank you!

This is through differentiation ( i was just checking the gradient) but you are not allowed to differentiate for paper 2. So you can ignore that

@@OALevelMathematics but than how do we draw a correct curve ?

@@OALevelMathematics can you please teach me how you found that point by using dy/dx so that if similar paper comes with similar curve I can draw it's min point

BAC is not sector, it is triangle.

This is derived from the cosine rule. Since the angle in between (G) is obtuse. The opposite side, C² > (a² + b²) cosine rule: cos G = a² + b² - c² ___________ 2 * a * b

@@OALevelMathematics ok thanks a lot sir !

You have to be precise. What are the questions you need help with?

Just a tip , i figured out things thinking about it later . Otherwise ur videos are lifesaving !

jazakillah you have solved my problem
