Does tangent of x equal cosine divided by sine?
No, it does not.
What is the anti derivative of negative cosine?
∫ -cos(x) dx = -sin(x) + C
What is the derivitive of a sine wave?
Negative cosine f(x) = sin(x) f'(x) = -cos(x)
Can you make cosine squared X divided by2 equal to cosine squared x with some constant?
You could just pull out the half: it will be (1/2) cos squared x.
What does x to the negative one equal?
x-1 means 1/x, also called the reciprocal of x.
Does cos x equal cos negative x?
Yes. Cosine is adjacent side over hypothenuse. Adjacent side is the same sign when x is positive or negative.
Why does cos negative theta equal cos postitive theta?
The cosine is simply the x-coordinate of the unitary circle. It helps to draw the circle, and the sine and cosine (x and y coordinates), to visualize this. The y-coordinate is the same for a positive angle and for the corresponding negative angle.
How do you differentiate a cosine function That is what is the derivative of the cosine of x with respect to the independent variable x?
The derivative of cosine of x is simply the negative sine of x. In mathematical terms f'(x) = d/dx[cos(x)] = -sin(x)
Why does cosine x equal cosine negative x?
This is going to require some visualization. Cosine is defined as the x-value on the unit circle. If you picture where a point would be, for example, at the angle of pi/6 (30°) you get a coordinate of (√(3)/2 , 1/2) so cosine is √(3)/2 and sine is 1/2 To find a negative angle you take the reflection across the x-axis. Since this does not chance the x-value, only the y, cosine does not change. The coordinates of -(pi/6) (-30°) are (√(3)/2 , -1/2). cos(-x) = cos(x) sin(-x) = - sin(x)■

What does sine times cosine equal?
Sin(x) cos(x) = 1/2 of sin(2x)
What is the period of the cosine function y is equal to 3 cos x?
y=3cos(x) peroid is 2pie
What does x to the negative one equal?
x-1 means 1/x, also called the reciprocal of x.
What does a negative times a negative equal?
A negative times a negative equals a positive.Positive.- x - = ++ x - = -
