GL everyone for P1 tomorrow

Thanks so much dude, you’ve saved my further maths grade

ILYSMMMM there was a qu like this FM Paper 1 today and I remembered this TYYY 😻😻

when do we use complete the square and when do we factorise?

Very well explained! However could u explain a trigonometric function to find the increasing or decreasing...like f of x = sin3x,x belongs to [0,pie by 2].     Edit:     Orrr....  F(x) =sinx +cos x,0 less than equal to x less than equal to 2 pie ...and also find the intervals😃..... Please

Exam in 20 minutes good luck everyone

How do you know when to factorise and when to complete the square ?

2:33, can we use the quadratic formula? to find dy/dx

4:43 You may like to review the graph. It cuts the x-axis at x=0 and 3, not 2.

For the last function would you not need to complete the square and state that 0<x<turning point x cordinate since after the turning point the function is actually increasing?

Why cant it be 0 is greater than "and equal to" x..etc.. Is it bcuz of dy/dx < 0?

what if the dy/dx is a quadratic eq and the its equal to zero? E.g 128x^2 +125x+1000 for x>0. Is it increasing/decreasing/neither ?

what if you have to work out the values of x for the function y= 2x-3 which is increasing?

Why is FM tomorrow I don't even know any of the topics, I hate my life 💔

FM paper 2 in 10 minutes 😭 saving my grade

Thanks man.

Can someone explain to me why in the second question the graph of the dy/dx equation that is a quadratic equation is drawn rather than that of the original equation, that is a cubic one. Please explain the concept behind this.
