d(y)/d(x) is totally correct notation. we call this as Leibniz's notation. Not like addition or division, there mainly 4 types of notations for differentiation. Leibniz's, Lagrange's, Euler's, and Newton's (dot) notation.

The point you're raising is true. d(y)/d(x) is one of the three main correct notations. But This instructor is talking about the way we should present the Leibniz's notation in word. That mightn't be "ඩී වයි බෙදීම ඩී එක්ස්" and should be "ඩී බෙදීම ඩී එක්ස්, වයි ". In fact, there's nothing huge to chase that hard in A/ls. But, tuition වලිනේ😅

Dude y is a function, in that notation we differentiate the function y with respect to x, it’s totally incorrect to say " dy බෙදීම dx ". We say it as derivative with respect to x( x විෂයෙන් y හි අවකලනය )not " dy බෙදීම dx ". IT’S NOT A DIVISION.

d/dx is a linear mapping on differentiable functions, but dy and dx are differential forms (1-form) , so it;s possible to divide dy/dx when dx is non-zero.

These guys are manipulating concepts of mathematics to down grade other teachers by taking the advantage of student's unawareness.

කිසියම් ශ්රිතයක් Y වශයෙන් ඇන්දම එම Y අවකලනය කරාම එහි SLOPE එක එනවා. Y අනුකලනය කලාම area එක එනවා. එමෙන්ම area එක ශ්රිතයක් වශයෙන් ගත්තොත් එය අවකලනය කලාම එයින් Y වල ශ්රිතය එනවා. SLOPE එකේ ශ්රිතය අනුකලනය කලාම Y වල ශ්රිතය එනවා. dy/dx කියවන්නේ ඩී වයි බයි ඩී එක්ස් කියල. එමෙන්ම බයි කියන එක බෙදනවා කියන තේරුම සහිතයි. එමනිසා dy බෙදීම dx කියන එකේ එතරම් ගැටළුවක් නැහැ.

Don't care he is an idiot, He failed to understand the fundamental theorem of calculus,. He says Integral means "Area" 😂😂.Anyway, d/dx is the differential operator, and the integral represents the opposite idea,. In fractional calculus, we can also describe the integral as d^(-1)/dx^(-1) which means the inverse operation of the derivative (Antiderivative). [I can't stop my laugh coz I am still writing for o/ls] - The only thing that he said truly is "If you can't understand the concept, it may be hard to deal with calculus stuff"

Its good research to look at the relationship between the area under a function and then rate of a function at a given point

He is also wrong on the definitions of derivative an integral. They are in fact inverse operation but never defined on geometrical facts, but rather from properties of real numbers. Further this could be extended to complex numbers and generally to both then we say on manifolds. While geometry could illuminate certain aspects and calculus is used in it but it never defines.

Yes. According to Lebiniz 's notation dy/dx is correct. But we must remember that it is not a division as it's a notation. But practically we use this notation. As teachers first we must teach our students the right thing. Srilankan A/L is a highly competitive examination. All the best!
