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.
To write in the mixed fraction you have to simply divide 8 and 4.
To right in the mixed number we need to know numerator, denominator and divisor.
So in your problem our divisor is 4,
so now lets divide it
So, now we have to write it as mixed number..
mixed number will be
Hope this helped you.. :)
