Which expression is equivalent to cos(1.4x) − cos(0.6x)?
givi [52]

Answer:

  A.  -2sin(x)sin(0.4x)

Step-by-step explanation:

At x=0, the given expression evaluates to zero.

For x near zero, the given expression is slightly negative. You know this because cos(1.4x) decreases faster than cos(0.6x), so their difference will be negative.

Of the answer choices, you can eliminate C and D because they are not zero at x=0. You can eliminate choice B, because it is positive for values of x near zero. The only viable choice is A:

   -2sin(x)sin(0.4x)

___

Of course, a graphing calculator can help you figure this out. See the attachment. The given expression is plotted using a solid red line; the answer choice A is plotted using blue dots.

Find f (-1) please and thanks
Hatshy [7]

Answer:

Step-by-step explanation:

f(x) = one of two values. There is a value given for what happens when x<>-1 and another when x is equal to minus 1. Which do you want?

Examine what f(x) means. It means that wherever you see an x value on the right, you put in the value shown for x on the left.

Try another example.

f(x) = x^2 - 2x

f(4) = 4^2 - 2*4     Whatever is shown on the left is put into the x on the right.

Same with your question

f(-1) means that the only possible answer is 5
