please help me solve the question below

if y=2x^2-sin2x find dy ---- dx

photomath app and solve it yourself

Synthax error

Thanks!.....but will it show the workings?

Na here dem go dey flex their muscle.. real life problem dem no fit solve.. all dey know na algebra, oji bi ke, summation x...
Nonsensical rubbish

who?

dy/dx = 4x – 2Cos 2x

This is straightforward. Devote time to studying Calculus.

dx

This is too basic....y'= 4x - 2cos2x
Study differential calculus in a textbook preferably KA Straud to learn from scratch

Chill boss.....the application is real and vast. As a Petroleum Engineer, calculus is integral in modeling multiphase flow through porous media, modeling rock failures... Calculus is fundamental in understanding well testing, reservoir engineering, etc. Likewise other areas such as studying stability of systems

in what way have you been able to solve pressing issues with ur mathematical knowledge?

In little ways, I have used it to perform reservoir simulation and estimation of storage capacity of depleted reservoirs in Niger Delta.
Also, with mathematics I've developed mechanistic models for predicting sand production in Niger Delta wells
I'm still a learner, mathematics is interesting with huge applications

Man i swear, in this life, Maths is my kryptonite. We no dey see eye to eye at all. On a totally unrelated note, Easter will soon arrive and we'll be seeing stupid posts like these lol...

The summary of my relationship with Maths...

I need no logic to tell me you're a brilliant chap

I taya no be small, my brother.

But like say dem dey fit relate all these equations to solving real life situations/problems, na dia e for make sense.

But all these ones na just to submit assignment or get A in exam and that's that.

Till today, I still dey wonder wetin I go use all the eigenvectors and eigenvalues, 4x4 matrices, partial fractions, integration by parts, complex numbers, Fourier series, Laplace transform, Karnaugh mapping and so many other nonsense wey I been study for Engineering do for real life...

Theoretical and hopeless Nigerian Engineers everywhere!!!

I think say na only..
How person go dey find joy in wetin no dey put food for there table still dey baffle me..

If it is not money, it is not making sense..

Oga, to know book dey sweet, but I would rather be a primary school drop out and a billionaire than to know book die and still be broke. Money is key.

lol... means nothing sweet like money ... welcome back bro at your old moniker

Lol. It's temporary. I will still return to my new moniker Martinez39s. Anyway, nothing sweet money. A man cannot enjoy life to the fullest without money.

I dey tell you!

IF IT DOESN'T MAKE MONEY; IT DOESN'T MAKE SENSE!!!

But even the lecturers wey suppose teach boys about making money no sabi anything about the topic sef.

Today they are going on strike and still dragging 2009 MONEY agreement with FG!!!

Can you imagine?!

If to say your useless father give you training your condition no go worse like this

you are very funny. do you know how to implement all these mathematical theories on hardware using c++ or python?

Yeah.

Why do you ask?

bluefilm:


Yeah.

Why do you ask?

then why do you say they are useless?
