Let

y = 3x

y' = 3(x)'

y' = 3(x1)'

y' = 3[1x(1-1)]

y' = 3(1x0)

y' = 3(1 x 1)

y' = 3

In general:

y = xn

y' nx(n-1)

What is the rate of change in the function y equals tan3x?

In this case, you'll need to apply the chain rule, first taking the derivative of the tan function, and multiplying by the derivative of 3x: y = tan(3x) ∴ dy/dx = 3sec2(3x)

What is the derivative of the quantity 3 times x plus 1 to the one half power?

Take the derivative of (3x+1)1/2First use the power rule on the entire function, then multiply it by the derivative of the inside:(1/2)(3x-1)-1/2(3) = (3/2)(3x-1)-1/2which can also be written as3/(2sqrt(3x-1))(sqrt stands for square root)


What is the derivative of e-3x?

f'(x)=-3the derivative of e is zero because its a constant. Derivative of -3x is -3. Bring the exponent of x down in front of the -3 and subtract the original exponent by 1. Ex. -3(1...which is the first exponent of the x)x^0(n-1 or 1-1=0)all this is -3(1)x^0x^0 is 1 so the derivative of -3x is -3

What is the derivative of 3x 4?

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "divided by", "equals".If the question is about 3x + 4 or 3x - 4, then the answer is 3.

What are derivatives?

In calculus, a derivative is basically the slope of a function. For example the derivative of 3x + 1 is 3, and the derivative of 5x2 is 10x. A derivative can also be a word derived (made) from another word. For example, "electricity" is a derivative of "electric". A derivative can also be a compound made from another compound (as in chemistry). Anything that "results from deviation" can be called a derivative. This basically means that if something is made from, or branches of something else, it can be called a derivative.

What is the derivative of tan x3?

If it's tan(x3), the the thingy is 3x2/(cos2(x3)) i think Else, if it's tan(3x), then it's 3/(cos2x) If you need more help with this, search "chain rule" and "derivative" on wikipedia.
