What does sinxcosx equal?
1/2 of sin(2x)
What is the limit of sinxcosx?
x can go to + or - infinity. f(x) is limited from + 1/2 to - 1/2.
Integral of cos squared x?
(x+sinxcosx)/2, can do it by parts or by knowing your double angle formulas
How do you find second derivative of a function?
All it means to take the second derivative is to take the derivative of a function twice. For example, say you start with the function y=x2+2x The first derivative would be 2x+2 But when you take the derivative the first derivative you get the second derivative which would be 2
How do you find the slope of a tangent?
Take the derivative of the function.
Which is the antiderivative of sinxcosx?
Using u-substitution (where u = sinx), you'll find the antiderivative to be 0.5*sin2x + C.
What does sinxcosx equal?
1/2 of sin(2x)

Formulae in derivative?
You will find several formulae in the Wikipedia article on "derivative".
What does the derivative at a point mean?
The derivative at any point in a curve is equal to the slope of the line tangent to the curve at that point. Doing it in terms of the actual expression of the curve, find the derivative of the curve, then plug the x-value of the point into the derivative to find the derivative at that point.
How do you find the mean of x over y equals a over b?
Find the derivative of Y and then divide that by the derivative of A
What is the limit of sinxcosx?
x can go to + or - infinity. f(x) is limited from + 1/2 to - 1/2.
Integral of cos squared x?
(x+sinxcosx)/2, can do it by parts or by knowing your double angle formulas
How do you find the derivative of x4?
The derivative of x^n is nx^(n-1) any n. The derivative of x^4 is 4x^3.
What is the purpose of finding derivative?
The purpose of finding a derivative is to find the instantaneous rate of change. In addition, taking the derivative is used in integration by parts.
Find derivative of sinx using first principle?
The derivative of sin(x) is cos(x).
