((-3)cos(y))(x2)
Well first of all you need decide what rule you should use. Now, because they're multiplied together I'm going to use the product rule which is -
(dy/dx)= f'g +fg'
remember to write everything out -
f=((-3)cos(y))
f'=((3)sin(y))
g=x2
g'=2x
so from here it's pretty simple, you just sub in the values you have for each letter, remember to use brackets!
so....(dy/dx)= ((3)sin(y))(x2)+((-3cos(y))(2x)
Now you just need to simplify and gather like terms -
(dy/dx)=3x2siny-6xcosy
=3x(xsiny-cosy)
And there you have it!
Remember to check this yourself cause its been a while since I've studied this so I might have made a silly mistake somewhere. ^_^ Hope this helps!
What else can I help you with?
What equals two squared?
4 squared means multiplied by itself so 2 squared is 2 times 2 which is 4 if i took 7 squared, that would be 7 times 7 which is 49
What does squared mean in math equations?
Times itself. For example, 4 squared would be 4x4 = 16. 5 squared would be 5x5 = 25 etc
What is 3.14159 times 3.14159?
that would be pi squared
Why is brayani wrong when she says when x equals 3 the value of 4x squared is 36?
She isn't. 4x squared is 4 times (x squared). That is, 4 times (3 squared) = 4 times 9. If you want it to be the square of 4x (which would be the square of 4 times 3, ie, 12), you have to write it as (4x)squared.
What does squared by 3 mean?
Well take (2 squared by 3) that would 2 times 2 which is 4, times 2 which equals 8 so (2 squared by 3) eqauls 8
6x squared plus 2x squared equals?
Oh, dude, when you add 6x squared and 2x squared, you get 8x squared. It's like combining 6 apples with 2 apples and ending up with 8 apples. So, in math terms, 6x squared plus 2x squared equals 8x squared. Easy peasy!
What does y times y equal?
That would be Y2 or Y squared.
How many times would Britain fit into the amazon basin?
Nearly 24 times. The Amazon is 5,500,000 km squared and Great Britain is 229,800 km squared.
What is the area of the circle if the radius is 5?
The area of a circle is equal to pi times the radius squared. So in your case it would be 5 squared, (25) times pi which is equal to ~78.5
How would you work out 40 squared?
'40 squared' simply means 40 times itself (40 x 40) which equals 1,600
What is 250 squared 3?
To find 250 squared, you calculate (250 \times 250), which equals 62,500. If by "squared 3" you mean to raise 250 squared to the power of 3, you would then compute (62,500^3), which equals 244,140,625,000,000.
What is X squared times x squared?
x2*x2...You would add the two exponents like this x(2+2), making it x4.
