Step-by-step explanation:
Derivation using Product rule : -
To find the derivative of f(x) = sin 2x by the product rule, we have to express sin 2x as the product of two functions. Using the double angle formula of sin, sin 2x = 2 sin x cos x. Let us assume that u = 2 sin x and v = cos x. Then u' = 2 cos x and v' = -sin x. By product rule,
f '(x) = uv' + vu'
= (2 sin x) (- sin x) + (cos x) (2 cos x)
= 2 (cos2x - sin2x)
= 2 cos 2x
This is because, by the double angle formula of cos, cos 2x = cos2x - sin2x.
Thus, derivation of sin 2x has been found by using the product rule.
Answer:
21
Step-by-step explanation:
I did the math.
Step-by-step explanation:
multiply 2 with the bracket numbers
6x+16=0
6x= - 16
x=-16/6
x= - 8/3
Answer:
9 3/4
Step-by-step explanation:
Pounds of bananas=2 7/8
=23/8
Pounds of apple=3 1/2
=7/2
2 bags of oranges=2 3/4 each
11/4 each.
Total pounds of oranges=2(11/4)
=22/4
Total pounds of fruits Marisol bought from the market=pounds of bananas+pounds of apples+pounds of oranges
=28/8+7/2+22/8
Find the L.C.M and add them
The L.C.M=8
Total pounds of fruits =28+28+22/8
=78/8
=9 6/8
Equivalent to
9 3/4
Answer:
2/8, closer to 0, and 2/4, closer to 1.
Step-by-step explanation:
With this question, you can make a number line, and number it 0-8. 2/8 is 2 away from 0.
