y=2 sin x cos x ? Question:what is the derivative of y=2 sin x cos x ? Implicit Differentiation :Consider a function f(x) its derivative with respect to x can be found by ddxf(x)=f′(x) For a function f(y) its derivative with respect to x gives ddxf(y)=f′(y)dydx Deri...
What is the derivative of f(x)=(x2+1)2 at (0, 1)? a.2x2+2b.2c.4d.6e.0 Derivative Differentiation of any function y=f(x) is the rate of change of y with respect to x written as dydx Here, we have to find the derivative of f(x) a...
What is the derivative of sin x minus cos x? d/dx(sinx-cosx)=cosx--sinx=cosx+sinx How do you prove the following identity sec x - cos x equals sin x tan x? you need this identities to solve the problem..that is something you have to memorized sec x= 1/cosx 1-cos2x= sin2x ...
What is the derivative ofsecx(tanx−secx)? The Derivative of a Function: The strategy of finding the derivative of a function is dependent on the format of the function. If the function is the product of two sub-functions then the product rule is the better choice. ...
What is the derivative of ln cos x? The derivative of the natural log is 1/x, therefore the derivative is 1/cos(x). However, since the value of cos(x) is submitted within the natural log we must use the chain rule. Then, we multiply 1/cos(x) by the derivative of cos(x). We...
What is the derivative ofsec−1(x+2)2=2(x+2)(x+2)−1? Differentiation of sec−1x=1xx2−1 Answer and Explanation:1 Lety=sec−1(x+2)2 Differentiation wrt x: {eq}\frac{dy}{dx}=\frac{1}{(x+2)^2\sqrt{(x+2)^4-1}} . \frac{d}{dx...
Find y' if y= ln( x^2 + y^2) I thought this was just a regular natural log derivative combined with the chain rule. So what I got was (2x + 2y)/ (x^2 +...
In the form of an FT it’s easy to filter sound. For example, when you adjust the equalizer on your sound system, like when changing the bass or treble, what you’re really doing is telling the device to multiply the different frequencies by different amounts before sending the signal ...
If µ(x) = ln(1 + x)/x, then for 0 x , µ(x) 1 and the derivative satisfies |µ'(x)| . Proof Note that µ(x) = 1 - x/2 + x2/3 - ... is an alternating series with decreasing terms, so for x 1, µ(x) 1 - x/2 1/2. It is even easier to see that...
What Is a Derivative? In calculus, a derivative is the rate of change at a given point in a real-valued function. For example, the derivative f'(x) of function f() for variable x is the rate that the function f() changes at the point x. It might change a lot, e.g. be very...
